Winter wheat oil, green manure management advice
In the past month (December), the temperature was high, rainfall was low (mainly in the late and late days), and the sunshine hours were insufficient, which had a negative impact on crop growth. According to the data from the Municipal Meteorological Bureau, the average temperature in December was 8.6°C, which was 1.9°C higher than the average. Monthly precipitation is 17.3 millimeters, which is 18.1 millimeters less than normal. Precipitation is mainly concentrated in the middle of the year, so the rainfall in mid-season is obviously more than usual, reaching 15.2 millimeters, which is 7.1 millimeters more than normal. The total precipitation in the upper and middle is only 1.9 millimeters. Sunshine hours are 92.6 hours, which is 53 hours less than the average. The high temperature promotes the growth of Ermai, green manure and rapeseed. It is very favorable to the growth of late-planted and late-planted crops. However, the lack of sunshine hours has a certain impact on the wheat's reproductive process.
According to the survey data of the "Xiaohan" solar terms, the average number of seedlings for wheat and barley was 267,600 and 312,700 respectively. The seedling height was 14.85 cm and 15.23 cm, the leaf age was 4.64 and 4.28, and the green leaf was 3.57 and 3.42; Compared with the average over the same period of the year, the total number of seedlings decreased by 107,200 and by 83,500, respectively. The height of seedlings increased by 0.17 cm and increased by 0.72 cm. The leaf age decreased by 0.38 and 0.49, and the green leaf decreased by 0.20 and 0.13. Eight rapeseed seedling inspection data were collected in eight counties, with an average leaf age of 14.01, green leaf 7.56, new leaf 2.31, leaf area 709.19 square centimeters, root neck thickness 0.96 centimeters, opening 37.37 centimeters; and the average of the previous five years Ratio: Leaf age increased 1.15, green leaves were flat, new leaves increased by 0.40, leaf area increased by 17.36 square centimeters, root neck thickened 0.12 centimeters, opening increased by 5.83 centimeters. Green fertilizer broad beans: basic seedlings 0.75 million, plant height 12.73 centimeters, 5.20 green leaves, 2.06 branches; compared with the same period last year, the basic seedlings increased by 0.16 million seedlings, plant height increased by 0.47 centimeters, green leaves by 0.28, branches by 0.15 One. Ziyun Ying: Basic seedlings 301,900, total seedlings 308,200, plant height 4.48 centimeters, green leaf 3.33, branches 0.03; compared with the same period last year, the basic seedlings increased by 35,600 seedlings, the total seedlings increased by 66,700 in the current period Seedlings, plant height increased by 0.99 cm, green leaves increased by 0.01, branches by 0.04. Cauliflower: 148,000 basic seedlings, 228,100 seedlings, 3.40 cm plant height, 3.90 green leaves, 0.54 branches; compared with the same period of last year, the basic seedlings were reduced by 21,000 seedlings, and the total number of seedlings in the current period was reduced by 324,500 seedlings. Plant height decreased by 0.96 cm, green leaves decreased by 1.45, and branches decreased by 1.73. The general characteristics of this period of the seedlings are:
1, wheat, oil basic seedlings (density) is more reasonable. During the winter crops sowing this year, Ermai promotes seedling reduction and seedling reduction techniques. The number of basic seedlings basically meets the technical standards. According to statistics, the basic seedlings of wheat and barley are 18.73 and 212,000 seedlings respectively, and the transplanting density of rape is 6,928, which is closer to the basic wheat. Seedlings 15-18 million seedlings, rapeseed transplanting density of 7000 or so technical requirements. However, it is higher than the technical requirement of 1 - 200,000 seedlings of barley.
2, faster growth. In the hot weather in December, winter growth accelerated. "Big Snow" - "Xiaohan" wheat and barley: the average total seedlings increased by 77,600 and 113,300 seedlings respectively, and the leaf age increased by 2.20 and 2.47; the total seedling growth value was reduced by 59,800 and a total of 23,600 seedlings from the same period of the year. Leaf age increased by 0.39 and 0.27. Rape: 2.31 leaf ages, 2.81 green leaves, 229.43 square centimeters in leaf area, 0.25 cm thicker root neck, and 8.59 cm open volume; the average growth rate in the same period from the previous five years: Leaf age minus 0.08, green leaf Increase 1.25, leaf area increased by 20.48 square centimeters, root neck increased by 0.08 centimeters, increase by 3.53 centimeters. Green manure: Broad bean plant height increased by 4.67 cm, green leaf increased by 2.22, and branching increased by 0.46; growth value was 3.21 cm higher than plant height over the same period of last year, green leaf increased by 1.63, and branching increased by 0.82. The total number of seedlings in Ziyun was increased by 52,500, and the plant height was reduced by 0.30 cm, the number of green leaves increased by 0.12, and the number of branches increased by 0.03. Compared with the growth value over the same period of last year, the total seedlings increased by 49,500, the plant height decreased by 0.65 cm, and the green leaves decreased. 0.95, branches decreased by 0.04. The number of total seedlings in the rose increased by 80,100, the plant height increased by 1.00 cm, the number of green leaves increased by 2.10, and the number of branches increased by 0.54. Compared with the growth value over the same period of the previous year, the total seedling volume decreased by 110,800, the plant height decreased by 0.30 cm, and the green leaf increased by 1.06. Zhang, branches increased by 0.41.
3, indicators of pre-winter seedlings that do not meet high yield standards. Due to persistent rain in November and mid-December, as well as the effects of insufficient light, the 1st to 3rd leaves of Ermai are generally slender, and the higher temperature promotes the growth of the leaves, resulting in large nutrient consumption and low tillering. The number of seedlings of wheat and barley in the current period was 267,600 and 312,700 seedlings respectively, and the number of wheat per plant was only 0.43, which did not reach the “Xiaohan†thirtieth annual number of 300,000 panicle seedlings, and the number of seedlings per plant was 1-1.5. The high-yield groups require and individual seedling indicators. There are few branches of green manure. The number of branchlets of “Xiaohan†faba bean, and Ziyunying and Huacai were only 2.06, 0.03 and 0.54, respectively. Excluding faba bean, Ziyunying and Cauliflower did not reach the target of 2-3 seedlings before winter.
4, Winter is relatively balanced. Due to the leadership's attention and the high temperature this year, which is conducive to crop growth, this winter's growing trend is relatively balanced. According to statistics, two wheat-type seedlings (5 leaf ages) accounted for 44.20%, secondary seedlings (leaf leafage 3-4 leaves) accounted for 52.30%, and three types (2-3 leaflets and below 2 leaflets) accounted for 4.50%. . There were 20.60% of the green manure (2-3 branches), 35.70% of the second seedling (1 branch), and 43.70% of the third seedlings (no branches). Early rapeseed planting, fertilization of more prosperous long seedlings (leaf area of ​​about 1000 square centimeters) accounted for about 23.80%, a type of seedlings (leaf area of ​​about 500 square centimeters) accounted for 35.50%, the second type of seedlings (leaf area 300-- 400 square centimeters accounted for 38.20%, and three types of seedlings (leaf area of ​​about 200 square centimeters) accounted for 2.50%.
At present, the growth of Ermai and rapeseed is basically normal. Affected by the warm winter climate, winter crops have entered the wintering growth stage centering on root growth. According to the climate characteristics of this year and the growth characteristics of Ermai, green manure and rapeseed, the management focus should be focused on Fertilizing the soil to promote root system and promoting balanced growth is the center, using warm winter air and favorable favorable conditions for promoting the growth of seedlings and laying the material foundation for the winter hair growth.
1, the difference between seedlings, hierarchical management. When it is appropriate to catch soil moisture, apply winter wax fertilizer. Winter wax fertilizer should be dominated by organic fertilizers, and compound fertilizer and BB fertilizer can also be applied to enhance the cold resistance and frost resistance of wheat, oil and green manure. For over-prosperous wheat growth, 30 grams of paclobutrazol should be sprayed to control the seedlings, or repression to prevent the seedlings from growing long and reduce the occurrence of frost damage. For the fields with insufficient growth before winter and severe freezing damage caused by low temperatures in the future, a part of available nitrogen fertilizer should be used to promote growth and increase nutrient accumulation. Generally, 500-750 kg of manure per acre, or 30 kg of compound fertilizer, or 20 kg of BB fertilizer, or 7.5--10 kg of urea, to ensure that the amount of fertilizer used before the end of winter is 60-- 70% of the fertilization before rape was 70%-75% of the amount of fertilizer applied in one year. Green fertilizer without application of phosphate fertilizer should pay close attention to additional phosphate fertilizer, 25 kg per mu.
2, clean up the ditch. For the current unobstructed trenches, timely organization of forces to clear the ditch, so that no rain ditch the ditch to ensure that the overwintering crop growth center - the normal growth of roots.
3, broken soil roots. Combine with the cleanup ditch system to timely complete the work of covering the ground with two wheat and rapeseed roots to improve the ability of freezing and cold resistance in the field
