Covering feces After winter wheat enters the wintering period, a layer of manure is spread along the ridge (people call it “warm ditch manureâ€), which can protect the wind, protect the earth, increase the temperature and prevent freezing, and supplement the nutrients for the young seedlings to grow green. Covering the thickness of manure to 3 ~ 4 centimeters is appropriate, manure approx. 5 cars per mu; manure is insufficient, the late barley, wheat, wheat, sandy wheat fields and sowing wheat fields to priority cover.
Pouring urine in the urine nitrogen 0.5%, phosphorus 0.13%, potassium 0.19%, organic matter 3%; winter pouring per acre 250 to 500 kg of fresh urine, can generally increase production of 25 to 50 kg of wheat, the effect is very obvious. The urination time generally starts from “starting winter†and ends at “clear tomorrowâ€, but it is the best time from freezing to before thawing. Before the soil is frozen, it can be poured at any time during the day, but it must be diluted with equal amount of fresh water to prevent burning of the seedlings. During the freezing period, the weather should be sunny and warm at noon or afternoon, and the soil should be poured when the soil is thawed. It can be directly poured without dilution with water. . Pouring urine, it is best to use squat or ditch gushing, apply immediately after the cover; if splashing, after the application should be timely scratching loose soil, remove the compaction, in order to protect the fat protection. The amount of urine poured is generally 500 to 750 kilograms per mu, up to a maximum of 1,000 kilograms. Pouring too much, easy to burn seedlings in poorly stricken plots.
The green leaves preserved during the overwintering period of grazing-free wheat can be used for photosynthesis after returning green. It is the main source of nutrients needed for the newly restored growth; once the wheat seedlings are fed by sheep and other livestock, the area of ​​green leaf and ground cover are reduced, and the freezing damage is reduced. Intensified, returning to spring and late in the spring, the percentage of tillers per spike and the grain weight per panicle decreased significantly. According to investigations by relevant authorities and manual simulation of leaf cutting experiments, the wheat fields eaten by sheep were reduced by 5.04% for light, 31.3% for three times, and reduced by 51.7% for continuous crops; the average reduction in wheat production by Mahan was 14.2% to 32%. The reduction in production of pig arches was 36.4%, and the production of simulated artificially cut leaves was 8.8%-23%. To this end, remind peasant friends that they must ban livestock.
Chemical control When wheat is frozen in the winter, the spraying of wheat seedlings with 0.3% to 0.5% chlormecan solution can inhibit plant growth and prevent or reduce frost damage.
