How to achieve high-yield cultivation of cauliflower? High-yield cultivation and management techniques of cauliflower
How to grow cauliflower? Cauliflower is a biennial crop cultivated in autumn and winter. It has a good sunshine, a warm and humid climate, avoids heat and drought, and its suitable temperature is 13 °C ± 7 °C. The suitable temperature for flower bulb formation is about 17-18 °C. The sowing period can be planted from the beginning of June. Most of the sows in this period are early-maturing varieties. After the time of listing in early September, it is a better variety to solve the autumn, and it is also one of the varieties with high efficiency. The following is the cultivation technique for early autumn cauliflower for your reference.
Cultivate strong seedlings
Cultivating strong seedlings is one of the key technologies for obtaining high-yield and high-efficiency cultivation of cauliflower.
(1) Seedbed setting
Select fertile land with good drainage and irrigation conditions, and arrange a seedbed for 40 square meters of seedbed area per 667 square meters. Apply 400 thousand non-fermented fine crushed high-quality ring fertilizer, 5 kg of ternary compound fertilizer, and disinfect and sterilize the soil with 30 g of carbendazim, and then deepen and level.
(2) Variety selection
The varieties of broccoli are Li Green, Tokyo Green, Zhongqing No. 1 or Green King. White cauliflower can be used in Fujian Wenxing for 60 days, 80 days, early snowball or dragon card for 60 days and 80 days.
(3) Determination of sowing date
It can be planted from early June to early July. 50 grams of 667 square meters.
(4) Sowing
First, the seedbed is watered, the seeds are broadcast live, sprinkled, covered with soil 1 cm thick, covered with shade nets or weeds and other shades, 6-7 days can be emerged.
(5) Seedling management
After the emergence of the seedlings, the sunshade net and the shade are exposed, and the small arch shed is covered and the sunshade net is covered. After the cotyledons are unfolded, the weeds are combined with the weeds, and the seedlings are 5-6 cm apart. Seedlings can grow a water after growing a true leaf, but not flooding. After 2 pieces of true leaves, 500 g of urea was applied in combination with watering 40 m2 seedbed. 5-6 true leaves 5-6 true leaves can be colonized. Watering and dicing 3 to 5 days before planting, transplanting with nutrient blocks. In this period, attention should also be paid to the treatment of pests and diseases.
2. Fertilizing the soil
667 square meters of soil and fertilizer 4-5 tons, ternary compound fertilizer 50 kg. The ploughing is flattened, and the planting raft is made according to the specification of 1.2 m in width and 30 cm in shovel.
3. Colonization
Planted in late June - late July. The planting hole was planted at a row spacing of 50×40 cm, and about 667 square meters were planted with about 3,000 plants. Choose strong seedlings, bring soil seedlings, plant enough water after planting, cover the shade net with small arch shed or greenhouse.
4. Field management
(1) After the planting, properly control the fertilizer and water before the heart is twisted, adhere to the drought and not water, and plough the soil several times to carry out the seedlings.
(2) After entering the rosette period, it grows rapidly. It is necessary to water the soil to keep the soil moist. The first 667 square meters of urea is 15 kilograms.
(3) Before the formation of the flower ball, it can be sprayed with 0.5% urea solution or increased production for foliar top dressing 1-2 times.
(4) At the beginning of the ball formation, the 0.2% borax solution is sprayed 2-3 times. Stop watering before harvesting.
(5) Pay attention to timely control of aphids, cabbage caterpillars, diamondback moth, beet armyworm, Spodoptera litura and downy mildew, black rot during growth.
5. Harvesting
By the end of August and the beginning of September, when the top flower ball is fully inflated, the edge flower buds are not harvested, and the lower part of the flower ball is cut with 10 cm and 3 to 4 young leaves, and the flower ball is cleaned with white paper. Packed into the box for shipping and sales.
The above are all the main points of the cultivation technology of cauliflower. Xiao Bian also reminds all the cauliflower growers that the growth process of cauliflower has special requirements for nutrients such as boron, molybdenum and magnesium, so be sure to pay attention.
