Key points of wheat planting technology

In order to increase the yield of wheat, we should do some preparatory work before sowing. Before sowing, we should improve the overall quality of the land. First of all, we will use a rotary tiller to rotary till the land is 5 to 10 cm to loosen the soil, and then break some large clods in the field completely. The second step is to select some high-quality wheat varieties, do enough germination tests and calculate the reasonable sowing amount.

Third, we should pay attention to sowing techniques. First of all, the temperature should be kept above 0 degrees, and the soil thawing depth should be 3-5 cm as the initial sowing date, so as to ensure that we have a high-yield period when sowing, and the time should be accurately grasped. The spacing of each ridge should be 15 cm wide, and it should be suppressed for 2-3 cm after sowing. When the weather is dry, it should be more than 4 cm, and the number of wheat ears per square meter is about 600 ~ 700. If the variety is precocious, the number of ears in wheat should be increased appropriately.

The fourth step is the basic management of seedling stage. When wheat seedlings are unearthed, it is necessary to find the land lacking seedlings as soon as possible, and make up the wheat seedlings lacking seedlings in time to avoid the lack of seedlings in the later period and affect the later yield. When sowing in the experimental field, the same variety should be selected. If it is a commercial grain field, early-maturing varieties can be supplemented. (2) When weeds appear in the fields, we should weed them. When there are broad-leaved weeds, dicotyledonous weeds and some wild wheat in the field, weed control should be carried out according to the situation of wheat seedlings. When the wheat grows to the third leaf, spraying treatment is the most suitable. 40 to 50 ml of 2.4 drops of butyl ester, 80 ml of 65% wild swallow, 5 ml of Bolin brand spray treasure and other plant growth regulators should be used per mu of land, and finally pesticides should be applied. (3) Topdressing: When you see which soil lacks base fertilizer, you should add it in time.

The fifth step is the treatment before wheat harvest. (1) foliar topdressing of wheat can avoid topdressing of wheat in the later stage, resulting in insufficient nutrients in the later stage and reduced yield, so as to strengthen irrigation intensity and make the grain of wheat ear bigger and fuller. (2) Pest control mainly refers to three aspects: control of scab, root rot and pest control.

The sixth step, we have to do is to harvest and subdue the land technology. (1) It is necessary to grasp the harvest time of wheat in time and pay close attention to harvesting and drying grain. (2) Dry the wheat in time to enter the market. We should dry the wheat in time to make the moisture content less than 14%, and it must meet the second-class quality of wheat purchased by the state in order to sell it at a good price. (3) After wheat harvest, we should arrange the land as soon as possible, loosen the land without subsoiling as much as possible, and strive for "spring rain" and "early spring to prevent autumn", that is, store the autumn rain to the maximum extent, make some preparations for the rainy season next spring, and give full play to the important role of soil "reservoir".

Seventh, we must clear up the land and apply chemical fertilizer in autumn. (1) Pay attention to the quality of the land, and plow the land deeply, preferably with a plow to increase the water storage capacity of the soil. (2) In the northern region, it is very cold every winter, so basically the land will freeze and frozen soil will appear every year. Before the land is frozen, it is necessary to increase the input of fertilizer, so that the land will have a certain nutrient guarantee when it is thawed in the next spring.
