    After the beginning of spring, winter wheat enters the regreening stage, followed by tillering stage to jointing stage, which are very critical for high-yield winter wheat and are also important periods for spring topdressing. The top dressing of spring winter wheat is mainly nitrogen fertilizer, and the phosphorus and potassium fertilizer required for winter wheat after the year depends on basal fertilizer, seed fertilizer and soil reservoir.

    After the winter wheat returns to green, it immediately enters the period with roots, leaves and tillers as the growth center, in the law of nitrogen nutrient absorption, although the number requirements are not too much, but the yield level of winter wheat in that year is very sensitive to the response to the abundance or lack of nitrogen nutrition in this period, which is also called the critical period of nitrogen nutrition, nitrogen nutrition is insufficient, there are fewer roots, small seedlings, especially less tillers, the group is not enough, and it is difficult to obtain high yield; At this time, if there is too much nitrogen fertilizer, resulting in large leaves, more tillers, too large groups, and too much consumption, there will be fewer grains and light grain weight in the future, and it is difficult to obtain high yields if it is greedy for green and late maturity. Therefore, under the condition of normal seedling condition, the total amount of topdressing nitrogen fertilizer should be controlled in the range of 6-8 kg of pure nitrogen.

Winter varieties of wheat are better sown around October 10-15 at temperatures of 16-18.

    2. Wheat planting method: (1) Select wheat varieties with good quality and high disease resistance, and soak wheat seeds with medicine before planting. (2) Choose the soil suitable for wheat planting, the planting soil should not be too dry and wet, carry out soil preparation before planting, and apply foot fertilizer.

    3) Choose the season time when planting, don't plant wheat when it's too cold. (4) Control the density of planting, and apply fertilizer reasonably according to the growth of wheat seedlings after planting. (5) Regularly inspect the planted field, find diseased plants and deal with them in time, or use pesticides for prevention and control, and strengthen field management.

    2. What fertilizer is good for planting wheat base fertilizer 1. It is better to use compound fertilizer for planting wheat base fertilizer, because compound fertilizer is rich in nitrogen, phosphorus and potassium, and sufficient base fertilizer can ensure the nutrients required for the normal growth of wheat. 2. How to apply bottom fertilizer: (1) In the case of nitrogen deficiency in the soil for planting wheat, choose a formula of high nitrogen and low potassium for fertilization, and apply about 150 catties per mu to ensure that the wheat has enough fertility.

    2) In the case of phosphorus deficiency in the soil for planting wheat, choose low-nitrogen and high-phosphorus compound fertilizer plus high-nitrogen fertilizer to apply at the same time, 100 kg of high-nitrogen fertilizer plus 40 kg of high-phosphorus fertilizer, which can be supplemented in both directions. (3) The soil condition of planting wheat is general, and you can use balanced compound fertilizer, 150 catties per acre.

    Winter wheat is a kind of wheat planted in the north, its characteristics, high quality and high yield, winter wheat growth needs a certain amount of high-quality fertilizer, in order to achieve high yield, excellent quality, planting winter wheat fertilization requirements:

    A base fertilizer: before ploughing the land, according to the plot, apply 2-5 tons of organic fertilizer per mu, and at the same time apply some diammonium phosphate, so that the wheat has enough nutrients in the whole growth period.

    2: seed fertilizer: when wheat is sown, a certain amount of seed fertilizer can be brought to the wheat seedlings, which can absorb nutrients in time after the wheat emerges, promote the formation of effective sin of wheat, make wheat accumulate more nutrients, promote the development of secondary roots, and help wheat safely overwinter.

    Three: top dressing: top dressing in all price segments of wheat growth, can make wheat obtain higher yield and excellent quality.

Wheat field agents are used in two peak periods, one is from mid-November to the end of December before the year. The second is from the end of February to the end of March after the new year. However, wheat field herbicides are still the best before winter, grass age is small and easy to eliminate, after the application of pesticides, one is that the grass is difficult to remove, the other is the amount of medicine, the effect can not reach the effect of the previous use, and it is easy to cause herbicide residues, so it is recommended to use the herbicide before the year, and the wheat field herbicide can be used at a temperature of 8-10 degrees. >>>More
