As the saying goes: "The wheat has no two." Mai Miao winter before the prolonged growth period, nutrient accumulation decreased, cold resistance decreased, not conducive to safe winter. According to the reasons for prosperous, wheat winter seedlings can be divided into four types: The seedlings of prematurely formed seedlings are long and narrow, draped, and the tillers are insufficient. The main stems and some of the large stalks of the stalks enter the two-edge period before the differentiation of the young spikes; these types of saplings tend to be weaker and weaker in the winter. At °C for a low temperature of about 5 hours, freezing damage occurs. Management measures: timely suppression. By suppressing, it can inhibit the growth of the main stem and the big scorpion, and control the length. When suppressing, pay attention to choosing a sunny day. If there is frost in the morning or when the dew is not dry, it cannot be suppressed to avoid injury. After the suppression, timely slashing, combined with watering, apply 15 kg of ammonium bicarbonate; if necessary, spray with 0.2% to 0.3% chlormequat solution, it can also inhibit prolonged and anti-freeze damage. The seedlings of Wang seedlings formed by excessive sowing are crowded, with poor individual development and few tillers. Management measures: firstly timely seedlings, establish appropriate group structure, promote individual development; combined with watering, supplement with appropriate amount of nitrogen and phosphorus quick-acting fertilizer to make up for excessive consumption of soil nutrients. The seedlings of Miao Miao, which are formed by excessive fertilizer and water, have many branches, the leaves are wide, and the fields are heavily concealed. Management measures: deep roots. When the main stem of the wheat seedling grows 5 leaves, it is 5 to 7 cm deep in the wheat line, cutting off some secondary roots, controlling nutrient absorption, reducing tillering, and cultivating strong seedlings. Some varieties of spring and weak winter varieties formed by improper selection of varieties are too early to plant, which will lead to long pre-winter. This type of seedling is most susceptible to freezing in winter. Management measures: On the basis of early drafting and suppression, the roots of the earth before the winter, or cover the "monticillary manure" to protect the wheat seedlings for safe wintering.
