Current Wheat Management Technical Measures
First, in the late winter regions, the seedlings should be grasped by the seedlings to suppress the long-term suppression of the pre-winter repression and the suppression of the wheat seedlings on the prosperous wheat fields with a large leaf age, a large total number of stems, and a large number of lands with extensive cultivation and rubbish. The overgrown shoots grow above the ground to ensure safe wintering of the wheat seedlings. The repression time should be selected in the afternoon on a sunny day so as to avoid frost cracking the wound in the morning. Wetlands should not be suppressed. In the warm winter southern region of the northern wheat region, the cultivation of cuttings can be controlled by cultivating roots and cutting off roots, but it is not suitable for cold areas in the north.
Second, timely pouring of the overwintering water in place: For wheat fields with less precipitation, insufficient bottom crops or unsuitable crops; for wheat fields with poor straw returning quality and site preparation quality, unrepressed after sowing, soil loosening, Still insist on emphasizing pouring overwintering water. Earlier winter water wheat fields, watering, timely scratching, breaking the soil compaction. As most soil moisture conditions in 2011 are better, the amount of watering can be reduced to 30 to 40 cubic meters per acre, which can play a solid role in soil, broken debris, and full of water.
Third, pay attention to control weeds and pests and diseases: As most wheat fields have ample moisture and more weeds, we should seize the opportunity to weather weeds better than sunny weather. At the same time, due to the high humidity in the field, wheat seedling diseases, such as sheath blight and root rot, are prone to occur. The diseased land can be compounded with pesticides such as triadimefon, carbendazim, propiconazole, etc. when spraying herbicides. , to achieve the effect of disease prevention and weeding. Insect pests, such as helminths, will decrease with temperature and winter water, but they may still occur in the spring.
Fourth, for wheat fields that are not poured into winter water, it is recommended to suppress the soil moisture before returning green in the early spring. At the same time, grazing prohibited in winter.
Fifth, the northwest plastic film wheat should be strictly controlled, to avoid excessive water consumption at the seedling stage. Paclobutrazol control modifiers are available when necessary.
