(1) timely early sowing: film sesame must be timely sowing, its suitable sowing date is from the end of April to early May. Although summer sesame seedlings have a large production increase effect by using plastic film, their high yield potential is limited and their economic benefits are also low. Of course, it would not be worthwhile to only plant spring sesame for one season a year. In order to increase the multiple cropping index and increase planting efficiency, it is possible to plant wintering and short-season vegetables (spinach, green vegetables, yellow cabbage, pea peas, early garlic, etc.) in front of sesame seeds, or use intercropping for intercropping. In the form of intercropping wheat and winter vegetables, after the early spring vegetables are harvested, the mulch film is planted and the wheat is harvested and then interplanted with summer cotton, sweet potato, and peanut.
(2) Choose middle and late mature sesame varieties with high yield potential: After mulching, the effective growth period of sesame is prolonged. Therefore, it is suitable to cultivate some middle-late-maturing sesame varieties with high tolerance to pods, diseases, and high yield potential. Only middle-late-maturing sesame seeds can be used to fully utilize the growing season and increase sesame yield.
(3) Increase fertilization materials, pay attention to fertilization techniques: film sesame long growth period, rapid growth, plant tall, must increase fertilization material to meet its demand for nutrients. At the same time, due to the increased likelihood of ground film sesame lodging, and the late fertility is also very easy to defertilize premature aging, so plastic film sesame is very particular about fertilization techniques. The principle of fertilization is: increase phosphorus and potassium fertilizers, control the amount of nitrogen fertilizer. Under this principle, high phosphorus, high potassium, nitrogen, and nitrogen:phosphorus:potassium are close to 1:1:1. When the yield of sesame per mu is more than 200 dry grams, the three are each about 20 kilograms. In the fertilization method, the basic fertilizer is the main fertilizer, supplementing flowering topdressing and foliar dressing. Half of the total P and K fertilizers and total nitrogen were used as the base fertilizer, and the remaining half of the N fertilizer was used as top dressing. The time, amount, and method of topdressing should be based on sesame seedlings and weather. Miao weak early application, multiple Shi; Miao Zhuang Shi Shi, late or not applied. When drought occurs, fertilizer can be combined with irrigation. When the soil moisture is good, the fertilizer solution can be infused in the ridge jack (or topdressing with a top-dressing gun). At the same time, it can combine with disease prevention and pest control for foliar dressing. In addition, the application of trace elements such as boron, zinc, and manganese fertilizers should be considered under conditions of high sesame production.
(4) Chemical regulation: Before sowing, 100 mg/kg to 150 mg/g dry soaked in (ppm) shrinkage or spraying at the seedling stage 150 mg/kg (ppm) shrinkage to promote seedlings. At the bud stage, we sprayed plant growth regulators such as foliar seedlings and sprayed shoots, and sprayed 0.1%-0.2% borax, 0.1% urea, 1% potassium dihydrogen phosphate to promote flower growth.
Freeze-dried Half Of Vegetables
Freeze-dried Vegetables into powder will not affect its nutrition. Normally heat-sensitive substances are lost at high temperatures. For example: traditional high temperature drying technology. Freeze-drying technology and sun drying, drying, spray drying and so on are drying technologies, different drying methods have different effects on the quality of products. Freeze-drying method has less damage to the product. The traditional drying method is above 0℃, while the freeze-drying technology is simply understood to sublimate the moisture of fresh food under the vacuum and low temperature environment, and retain its original nutritional composition, appearance, size and other biological characteristics.
