Early spring oil wheat cultivation techniques
Oiled wheat is a green leafy vegetable that has been popular in the market in recent years. It is a variant of lettuce, which has two kinds of sharp leaves and garden leaves. The color of green wheat leaves is green, and the stems and leaves can be eaten. After frying, they still retain crisp green fragrance. They can also be used as soups, which are favored by the market.
The cultivation of oil-grained wheat has the following characteristics. First, the requirements for the growth environment are not strict, the growth period is short, and the cultivation is easy. No matter whether it is a pipe shed or open field, it can be cultivated. Second, pests are light and pesticides are rarely used. It is a safe and healthy vegetable. The economic efficiency is relatively high.
Cultivation techniques are as follows:
One, land preparation
Before the planting, the land is deeply plowed, with an application rate of about 3,000 kg of fertilizer per acre, 10-15 kg of urea, 15-20 kg of diammonium phosphate and 5-10 kg of potassium sulfate. The fertilizer and the soil are fully mixed and made into a flat or sorghum, with a width of 1.5-2 meters and a length of 10-20 meters.
Second, planting seedlings
In the early spring, planting seedlings are planted in the middle sheds in January-March, and standard sheds are built. In the middle, a ditch is opened, deep plowing is built, water is poured into the bottom, seeds are spread in the pots, and the seedlings are covered to cover the seeds. Tiled plastic film (2 layers of film l layer of film), generally 10-15 days of emergence, every time the temperature of the seedlings emerged at low temperatures. After the seedlings are lifted, the plastic film is removed, and ventilation is performed. During the day, the seedlings must be protected against high temperatures and freeze-dried at night; the proper temperature for the germination of the seedlings must be 15°C to 20°C, and should not exceed 25°C or less than 8°C. Therefore, it is necessary to germinate and sow when cultivated, otherwise it is difficult to guarantee the success of nursery. Seed soaked with water for 4-6 hours, and then picked up and drained, wrapped with gauze, the following methods can choose to germination: 1 thermos ice cube germination method: the soaked seeds, hanging in the bottle, in the bottle Add clean water and ice cubes, keep at 15°C-20°C, rinse 1 time every other day and insist on changing water and adding ice cubes. 2 refrigerator low-temperature germination method: the soaked seeds, into the refrigerator at 15 °C -20 °C, and insist on washing 1 times a day. The above germination can be sown by 60%-70% budding for about 2-4 days.
Seedlings drenched when sowing. Due to the small brown seeds, fine soil must be added before sowing. Spreading, sowing after the sieving of fine soil, such as the days of heat and then covered with straw, the weather is covered with a layer of film, after emergence, need to peel off the cover. Summer emergence is faster, about 3-4 days, and winter is slow to emerge. It takes about 7 days. When the seedlings grow to 3-4 true leaves, they can be transplanted to Daejeon.
3, planting density
In order to obtain higher yields, it can be properly planted in close to 25,000-30,000 plants per acre.
Third, field management
Planting water when planting colonization, usually after 3-4 days can be slow seedlings. After easing the seedlings, it is used with watering and rushing to raise the seedlings (15 kg of urea per acre), and the post-reuse of the tree-fertilizer (30 kg of urea per acre) is applied. After culturing the seedlings, timely cultivating and deep boring are encouraged to facilitate seedlings and promote root development. Throughout the growth and development period, it is necessary to keep the fields moist and the soil loose. During the growth period, a large amount of fertilizer is needed. Normally, a nitrogen-based decomposed organic fertilizer is sprayed every 7-10 days to promote leaf growth. Fertilizer should be stopped 1 week before harvest. Avoid dry soil in high temperature season, spray in the morning and evening when water shortage, keep the leaves fresh.
IV. Pest Control
Seaweed prone to downy mildew, 72% metalaxyl MnZn wettable powder 400-500 times spray control, or 72% Pryco 1000 times spray control. When the leaf miner is harmed, it can be sprayed with 1% of fly locust net emulsion 1500 times liquid.
V. Harvesting
The harvesting standard of oil-and-grained wheat and vegetables is relatively loose, and it can be harvested from the 14-16 leaf, and it will be harvested and listed according to the price to increase the yield and increase the income. If harvesting is too early, the yield will be low, and it will be picked up later, affecting the quality. Harvested in the early morning.
