“The main constraints of dryland wheat production are seasonal drought and poor soil, especially spring drought. The management of wheat fields in spring should be focused on the conservation of soil and the raising of alfalfa, supplemented with top-level fertilizer, and comprehensive prevention and control of diseases, pests and weeds. Ensure the stable production and high yield of dryland wheat." Zhang Baojun told reporters.
In response to the spring management of the dryland wheat region, Professor Zhang Baojun reminded the farmers' friends to do the following five tasks.
At the top of the list, conservation is the most important measure for dryland wheat. "Spring buckwheat hair, wheat seedlings green oil." Top soil can loosen the soil and cut off the capillary to form a dry earth barrier layer on the surface of the earth so as to effectively retain the soil moisture, which is particularly beneficial to the growth of wheat.
Top Ling top dressing, promote weak to strong base fertilizer deficiency, seedling yellow seedlings weak wheat field, can be combined with the top Ling Xiaoyu or after the rain to pick up fertilizer, per acre can be applied topdressing 4~5 kg of urea, or along ridge ditch irrigation shed , to promote weak seedlings to grow strong. For dryland wheat fields where the pre-winter group is too large and the soil fertility is relatively high, it is not suitable to top-dress fertilizer in the returning green season to prevent prosperous growth.
Rolling and lifting the lotus root to prevent lodging of the early spring wheat before and after greening can promote the development of wheat roots, increase the wheat's own drought resistance, and can inhibit the growth of wheat stems. "Mule in March, bucket of water." Rolling pressure should be combined with slashing, generally after the suppression of squatting, in order to achieve the purpose of Panasonic, lifting smashing, smashing, and warming. It should be noted that the rolling time should be before and after sunny noon, and should not be carried out in the cold wet morning.
Scratching and loosing soil, weeding, warming wheat, and wheat fields before the jointing period are sealed, can eliminate weeds, protect the soil and improve the ground temperature. When plucking, it is necessary to pay attention to the place and the system of seedlings. For late-seeding wheat fields and weak Miao fields, we should plan shallow shrubs to increase soil temperature and promote weak seedlings to grow strong; for Wangmiao wheat fields, we should appropriately take roots and cut off roots, control long seedlings, reduce ineffective tillering, and promote root shoot down. Change seedlings for strong seedlings.
Prevention and control of pests and diseases, chemical weeding to do wheat stripe rust, sheath blight, wheat bran and other pests and diseases forecast and prevention and control work. Pay attention to chemical weeding during the return period. Special attention should be paid to strengthening the forecasting and prevention of wheat stripe rust, and continue to vigorously popularize the prevention and control experience of “accurate monitoring, reconnaissance with drugs, discovery of one point, control of oneâ€, early detection, and early prevention and treatment.
