Wu Shouguo from Wuwei County, Anhui Province, said on December 16 that he sowed wheat on October 18 and used 15 kilograms per acre. Due to the high temperature and adequate rainfall in the early stage of wheat growth, the emergence rate was high, and the wheat seedlings grew vigorously. Now, there are 3 to 5 tillers for wheat. The height of the plant is up to 20 cm and the leaves drape. He asked if there are any precautions to be able to suppress the wheat fields.
After sowing wheat this year, the temperature is high, soil moisture is suitable, and the rate of emergence is high. Some of the early crops in our province have grown vigorously. In particular, large-scale seeding fields have more basic seedlings, larger populations in the field, and more prosperous trends, and are prone to freezing injury in low temperatures. For this part of the plot, measures can be taken to control it. Repression is one of the measures to control the growth of wheat seedlings. Repression can inhibit the growth of wheat main stems and large shoots, narrow the gap between tillers, control the occurrence of excessive tillers, achieve the purpose of control and prosperous growth, and at the same time can crush the clods and compact them. Simmering surface, bridging the earth seam, is conducive to water conservation, fertilizer conservation, insulation, antifreeze and seedling protection.
The wheat field with no single tillage and no single tillage cannot be repressed, and the wheat field where the wheat seedlings have been tillered, grows up, or grows up can be suppressed before winter freezing, or after thawing in the spring and before jointing. For early sowing, large sowing, basic seedlings per acre of about 400,000, wheat seedlings crowded each other, leaves are thin, there is little or no delivery of false Wang Miao field, should be sparse seedlings, and fertilization in the wheat field after fertilization as appropriate Until the wheat grows strong and then suppress it. For early sowing and suitable sowing, the basic wheat seedlings with an acre of about 200,000 per mu can be repressed in due course; due to suitable temperature, water and fertilizer, there are many wheat tillers, and the leaves are dark green and thick, and the population is 800,000-900,000. If it is still prosperous after repression, it may be repressed or repressed several times, combined with deep-rooted cultivation to cut off roots, control and prosperous growth.
The repression can be carried out using stone rakes or iron pressure rollers or oil drums with appropriate amount of water, artificial stamping and other methods. The direction should be the same when repeatedly pressing, and can not be reversed pressure, otherwise it will seriously damage the wheat seedlings. Do it before and after noon on sunny days. Don't do it in the morning when there is frost and the soil is too wet to avoid hurting the seedlings and causing the wheat field to close. After repression, it is best to take care of the soil with loose soil. For prosperous wheat fields that have not been poured with water, timely winter irrigation (with an average daily temperature of 3°C or higher) after suppression and control of wang, promotes root growth and transformation and escalation.
According to Wu Shouguo’s report, wheat was sown on October 18, with a seed quantity of 15 kilograms per acre. The planting time was early and the seeding volume was large, and there were more basic seedlings in the field. For this type of excessively prolonged growth of the basic seedlings, it is best to sparse the seedlings, and fertilize them according to the growth conditions of the wheat seedlings after the seedlings are thin, and then transform the wheat seedlings and then suppress them immediately before the freezing. The lower temperature in the near future, the growth of wheat seedlings will be significantly inhibited.
