Early spring oil and wheat cultivation techniques

Oily wheat is a green leafy vegetable in the popular market in recent years. It is a variant of lettuce, with two types of sharp leaves and garden leaves. The oily wheat leaves are green and green, and the stems and leaves can be eaten. After the frying, they still retain the crispy green fragrance. They can also be used as soups. They are quite popular in the market. Today, we will introduce the cultivation techniques of early spring wheat and wheat.

 

  Early spring oil and wheat cultivation techniques:

 

1. Land preparation: deep land before planting, about 3000 kg per mu of farmland, 10-15 kg of urea, 15-20 kg of diammonium phosphate, 5-10 kg of potassium sulfate, and smashing after spreading the ground. Mix the fertilizer and the soil thoroughly to make a flat or high sorghum, 1.5-2 meters wide and 10-20 meters long.

Second, sowing seedlings: Early spring sowing in the shed in the middle of 1-3 months, seedlings are planted in the shed, 2 sheds are built in the standard shed, 1 ditch is opened in the middle, deep shovel is built, the bottom water is poured, the seeds are spread in the sputum, and the seed mud is covered to cover There is no seed for the degree, flat plastic film (2 layers of film l layer of mulch), generally 10-15 days of emergence, every time the rain and cold time emerges longer.

  

After the seedlings, remove the mulch film, ventilate and ventilate, prevent high temperature injury during the day, and prevent freezing damage at night; because the germination temperature of the oil wheat seed is 15 °C-20 °C, no more than 25 °C or less than 8 °C. Therefore, when cultivating, it is necessary to germination and sowing, otherwise it is difficult to ensure the success of seedling raising. First soak the seeds in water for 4-6 hours, then pick up and drain, wrap them in gauze, and choose the following methods to germination: 1 thermos ice germination method: immerse the seeds in the bottle, in the bottle Add water and ice, keep at 15 °C - 20 °C, rinse once every other day and insist on changing water and adding ice. 2 refrigerator low temperature germination method: the soaked seeds, put into the refrigerator at 15 ° C -20 ° C, and insist on washing once a day. The above germination takes about 2-4 days, and 60%-70% of the germination can be sown.

The nursery is watered during sowing. Due to the small brown color of the seeds, fine soil must be mixed before sowing. Spread, after the sowing, cover the fine soil, such as the hot day and then cover the grass, the cold is covered with a layer of mulch, after the emergence of the need to remove the cover. Summer emergence is faster, about 3-4 days, and winter emergence is slow, it takes about 7 days. When the seedling grows to 3-4 true leaves, it can be transplanted to Daejeon.

  

Third, field management: planting water when planting, usually 3-4 days after the seedlings can be slowed down. After the seedlings are slowed down, the seedlings are applied with watering (15 kg of urea per acre), and the heavy fertilizer is applied at the end (30 kg of urea per acre). After planting and slowing down the seedlings, timely cultivating and deep ploughing will facilitate the seedlings and promote root development. During the whole growth period, the field should be kept moist and the soil loose. During the growing period, the amount of fertilizer is large. Generally, the fertilized organic fertilizer mainly based on nitrogen fertilizer is sprayed once every 7-10 days to promote the growth of the leaves, and the fertilization should be stopped one week before harvesting. Avoid soil dryness during high temperature seasons, spray in the morning and evening when water is scarce, keep the leaves fresh and tender.

Fourth, pest control: oil wheat vegetables are prone to downy mildew disease, the initial stage of the disease with 72% metalaxyl manganese zinc wettable powder 400-500 times liquid spray control, or 72% Plex 1000 times liquid spray control. When the leaf miner is in danger, it can be sprayed with 1% fly ash emulsifiable concentrate 1500 times solution.

 

In the early spring, the cultivation techniques of the oil and wheat vegetables are introduced here. The harvesting standards of the oil and wheat vegetables are relatively loose, and they can be harvested from 14-16 leaves, and the prices are harvested and listed to increase the yield and increase the income. If the harvest is too early, the output will be low, and the middle and late pick up will affect the quality. Harvesting takes place in the early morning.
