Currently our county wheat has approaches into the over-wintering stage, do a good job in the winter before pest control and field management is very important. For days, the county agriculture agricultural technology experts into the fields, farmers work on the prevention and control of plant diseases and insect pests of wheat tillering stage.
Tillering stage is one of the important period, constitute the total number of ears of wheat and a variety of concurrent harm of diseases and pests, diseases and pests to breed the important period of accumulation. Because the recent my county at higher temperature and part of the plot wheat appeared prosperous long phenomenon, and led to a small amount of diseases.
In view of the current characteristic of wheat plant diseases and insect pests, and to ensure that food production safety, the county agriculture bureau adhere to the early prevention, early, early prevention and control plant diseases and insect pests prevention and control work, completes the current wheat resident county agricultural technology personnel, carry out technical guidance, to help farmers solve technology and medical problems.
Wheat in mong long mainly has four reasons: a, dense planting seedlings: due to the large amount of planting of basic seedlings caused by too much of the difference moderate growth. Second, earlier planting seedlings: because of early sowing, wheat seeding prosperous long, springness varieties will elongating stage, early weak tolerance to cold, winter easy to freeze to death. Three, thin planting seedlings: seeding quantity too little, or lack of miao DuanLong, leading to excess tillers per plant wheat seeding, small tillers, ahead of time than with leaf emergence of date, developed root system, but the plant is not high. Seedlings in more than four, nitrogen, available nitrogen, especially recommended or kind of fertilizer consumption is large, and the temperature on the high side, easy to form seedlings. Growth of seedlings are mostly over, incoordination between organs, the accumulation of sugar in the body, less vulnerable to cold in winter. For the phenomenon of wheat seedlings in hydrophobic miao immediately or rolling, controlled water fat, inhibit growth.
