The suitable soil humidity for watering and supplementing irrigation to promote the emergence of seedling wheat is 70% -80% of the water holding capacity in the field. For wheat fields that are not watered before sowing, have poor surface moisture, and are difficult to ensure emergence, they should be watered as soon as possible to promote seed germination and seedling growth and ensure the basic seedling volume. After sowing, the wheat field that has been rained or has been covered with water in the head should be demarcated in a timely manner when the conditions are appropriate to break down the compaction. Wheat fields with suitable conditions should be avoided.
Check seedlings and replant them. Promote seedlings during the emergence of whole wheat. Promptly check the seedlings during the emergence of whole wheat. For places lacking seedlings and ridges, soak seeds with the same variety of seeds and replant them early; When transplanting, the depth of soil cover should be grasped, "No pressure on the top and no whiteness on the bottom". After the seedlings are planted, they should be watered properly, and properly fertilized to promote early delivery and ensure the whole seedlings.
According to local conditions, classified management has been carried out before the sowing or suitable conditions, good quality sowing, normal emergence of wheat fields, generally no field management within 1 month after sowing, wheat tillering period to the beginning of wintering, During the month, temperature changes, precipitation, soil fertility, moisture and population size, and seedling growth, etc., take targeted winter management measures.
For wheat fields with poor soil strength, insufficient application of base fertilizer, and symptoms of fertilizer deficiency, we should seize the opportunity to fertilize and water before winter, and plough the soil in time to promote root growth. Wheat fields with sufficient bottom fertilizer, normal growth, and suitable soil and soil conditions are generally not topdressed and watered before winter, and are only paddyed. Prosperous wheat fields suitable for soil moisture, do not topdress and water before winter.
For late-seeding weak seedlings, it is not advisable to irrigate winter water when the bottom soil is sufficient, so as not to reduce ground temperature and affect seedling growth. You can lightly soil the soil, increase temperature and maintain soil moisture, and promote root growth. The main direction of pre-winter management is based on Miaoquan and Miaoyun, to promote root growth, increase weakness, control weak and prosperous, cultivate strong seedlings, and ensure that seedlings are safe for winter.
The suppression of cultivating in mid-tillage, and promoting the cultivation of Miao Zhuang at each appropriate time after rainfall or watering, to eliminate compaction, improve soil aeration conditions, and promote the healthy development of root moth. If the group is too large and prosperous, you can deepen the roots or suppress it, and control it to grow stronger. For wheat fields with extensive tillage and large amounts of rubbish, the ground is suppressed before freezing to crush the rubbish to make up for cracks, which can play the role of heat preservation and preservation. Pressing wheat should be done after noon to prevent frost from cracking the seedlings in the morning. Saline-alkali land should not be suppressed.
