What are the spring management of wheat? People eat food for the day, and wheat is one of the staple foods of human beings. Of course, there are many people who grow it. Now in the spring, Xiaobian said that in the early spring, how to manage wheat wheat scientifically and rationally, please continue to look down.
[Management measures for spring watering and fertilization, pest control of wheat]
I. Planting management matters
Early spring is not only a key time for the transformation of wheat seedlings, but also an important period for determining the number of spikes and the number of grains in wheat.
1. Watering and fertilizing
a. After the soil is frozen, through the suppression of slashing, topping, etc., to raise and protect the raft;
b. For weak seedlings, after the soil is re-slurry, nitrogen fertilizer should be applied to promote the early development of weak seedlings;
c. For the strong wheat field, after the wheat is up to the rain during the jointing period, the rain and topdressing measures are taken. The main topdressing operation is: 12-15kg of urea per mu, for the soil without the phosphorus fertilizer, so in the nitrogen fertilizer. Increase the diammonium phosphate, which is conducive to the growth of roots and improve the drought resistance of wheat; the soil should be fertilized in time after thawing, 20kg of urea per mu, and 30kg of nitrogen and phosphorus compound fertilizer for the phosphorus-deficient plot, which will help accelerate wheat seedlings. Growth; spraying plant cell membrane steady-state agent, sodium nitrophenolate and other plant growth regulators in the wheat greening period, which is conducive to promoting the occurrence of tillering and increasing the tillering rate; in the jointing stage of wheat, according to the growth of wheat seedlings, Topdressing nitrogen fertilizer or nitrogen and phosphorus compound fertilizer to increase the number of kernels.
2, antifreeze and light transmission
For the wheat fields with severe frost damage during the winter period, the management principles of early management and early development are adhered to. The main measures are: in the early spring season, timely buckwheat or rowing of wheat, clearing dead leaves, improving the ventilation and light transmission of wheat fields, and promoting new life. Leaves accelerate growth.
3, squatting and soil
a. The planing has good effects of warming, protecting and killing grass, and should be used as the primary task of early spring wheat field management.
b. In the early spring, the favorable season is at the top of the peak period, that is, when the surface soil is frozen at 2cm, the stroke is started. Before the jointing, the paper will be drawn one or two times. In the early spring, the depth of the first stroke should be lighter, so as to prevent losses. Roots and cold currents freeze damage. When the temperature gradually rises, the depth of the stroke is also deepened, so that the thinning, smoothing, flattening, and smoothing are carried out without leaving the wheat, and the wheat seedlings are not pressed, which is beneficial to root growth and removal of weeds.
Second, the prevention and control of pests and diseases
1. Prevention and control of wheat diseases
a, powdery mildew: can be sprayed with powder rust and water, used for 35-50g per acre.
b. Scab: In the wheat heading stage, 40-50g of carbendazim active ingredient per acre is used to uniformly spray the wheat ears.
2, wheat pest control
a, locusts: use 2.5% enemy killing emulsifiable oil l0-l3ml per mu, and evenly spray control after watering. It should be noted that due to the large number of mites in wheat filling period, it is necessary to observe the control effect after one week of spraying. There are more aphids, and one more spray can be prevented.
b. Mai Spider: When the spider is flourishing, use 40% dimethoate emulsion l000 times solution to spray and control around noon.
3. Wheat grass damage prevention
a, broadleaf weeds: herbicides can be: hummer, grassy spirit, new Yanling, oatmeal, chlorpyrifos, He Dazhuang and so on.
b, broadleaf weeds and grass weeds can be mixed with herbicides: chloromeron, chlorsulfuron, metsulfuron, isoproturon, Ligulong, pucaojing and Hetianjing.
Soy lecithin powder is a substance derived from soybeans that is commonly used as an emulsifier, stabilizer, and thickener in food products. It is a natural source of phospholipids, which are essential components of cell membranes. Soy lecithin powder is often added to chocolate, baked goods, and other processed foods to improve texture and prevent separation of ingredients. It is also used in the production of dietary supplements and pharmaceuticals. Soy lecithin powder is generally considered safe for consumption, although some people with soy allergies may need to avoid it.
