Main points of cultivation techniques for early maturity of edamame in greenhouse
The whole land is made of shovel, and the neutral soil with deep soil and good drainage, rich in calcium and organic matter is planted in the greenhouse. One month before sowing, 1000 kg of cooked chicken manure per mu and 15 kg of compound fertilizer imported by three yuan. The ground preparation is flat, the width is 2.1 meters, the groove width is 30 cm, and the depth is 20 cm.
Seed selection and selection of precocious edamame varieties suitable for local cultivation. From the end of January to the beginning of February, the weather is selected without the influence of strong cold air, and the amount of seeds per acre is 5-6 kg. On-demand, the plant spacing is 25 cm, and the sowing depth is 3 to 5 cm. 1 week before sowing, the greenhouse film was buckled, and the soil was covered after sowing. Each acre was sprayed with 5% acetochlor EC 80-100 ml and water 30-40 kg, covered with mulch or small arch shed.
Pay attention to anti-freezing and warmth in the early stage of field management, and strengthen ventilation and ventilation in the later stage. After emergence, choose a sunny day and break the membrane to release the seedlings. The shed temperature before emergence is maintained at 15 ~ 25 ° C; the shed temperature in the early growth period is maintained at 20 ~ 25 ° C; the shed temperature during the flowering period is maintained at 20 ~ 28 ° C. Seedling is generally not fertilized. When the leaves are shrunk, choose a sunny day at noon and use 50 grams of yellow leaf enemy micro-fertilizer plus 30-45 kg of water. The flowering period was sprayed with a 0.5% potassium dihydrogen phosphate aqueous solution, and sprayed again every 7 to 10 days. In the period of falling flowering, 10 kg of urea per acre is added with water. It is not advisable to water the seedlings before sowing. When the seedling stage is too dry, it can be watered in an appropriate amount to promote hair roots. During the flowering period, the soil is managed in a dry manner, and the pods are managed in a wet stage.
Prevention and control of pests and diseases, prevention and control of blight, 200 grams of smoked bacteria per mu in the seedling stage, sprayed with chlorothalonil and carbendazim in the 4 leaf stage, spray once every 1 week, a total of 2 sprays .
Appropriate harvesting will be harvested at the end of April and early May, and the pods will be harvested in batches.
Single Packed Yellow Waxy Corn Cob
For the most common waxy and sweet corn on the market, waxy corn has a higher nutrient content than regular corn, containing 70-75% starch (and almost all straight-chain starch), more than 10% protein, 4-5% fat and 2% multivitamins, with more grains, VA, VB1 and VB2 in protein than rice, with the highest fat and VB2 content. Yellow maize also contains carotenoids, such as rice and wheat. The molecular weight of waxy maize starch is more than 10 times smaller than that of ordinary maize, and the starch makes glutinous rice sticky and soft, softer than ordinary hard maize. It is more than 20% more digestible to eat than regular maize and it is suitable for people with less than perfect teeth. At the same time, it is not suitable for diabetics because of the very high content of straight-chain starch (a polysaccharide).
Waxy maize is also known as sticky maize. The grain has coarse, waxy endosperm, similar to shiny, glassy (clear) grains such as hard and dent maize. Its chemical and physical characteristics are controlled by a recessive gene, which is located on chromosome 9. 100% of the starch in the endosperm is straight-chain starch.
