When is the best time to hit nutrients on wheat,

Generally in the booting stage and the filling stage! The effective grain filling period can be extended, and the effective spike number, grain number per spike and 1000-grain weight can be increased, so as to increase the yield

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.

Spring wheat varieties were sown around October 10-15 at a temperature of 16-15. Semi-winter wheat varieties were sown from September 27 to October 12 at a temperature of 16 to 17. Winter varieties of wheat were sown around 10-15 October at temperatures of 16-18. 1. What is the best time and temperature to grow wheat? 1. Spring varieties of wheat are better sown around October 10-15 and when the temperature is 16-15; Semi-winter wheat varieties were sown better from September 27 to October 12 at a temperature of 16 to 17. 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.

1. The first topdressing of winter wheat, for the seedlings of the winter wheat regreening period after the beginning of spring, chase nitrogen fertilizer once when the wheat grows up, a bag of ammonium carbonate is 100 kg per mu, and the application method adopts ditching fertilization, soil burial combined with cocoon wheat and watering method.

2. The second topdressing of winter wheat is to apply 24 kg of urea per mu and water when the wheat grows to the second leaf.

3. The third topdressing of winter wheat, in early May, the early stage of winter wheat heading and flowering, and then topdressing urea 10 kg per mu, the main purpose of fertilization at this time is to make winter wheat obtain higher yield and better quality results.

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.

When is the best winter wheat fertilization time, after the beginning of spring on February 4, sprinkle urea or ammonium bicarbonate after rain, depending on the fat and thin wheat seedlings, the wheat seedlings are green and strong but too small, and there is a kind of wheat seedlings thin and yellow can be topdressed, and 10 to 15 catties are sprinkled on an acre. On April 5th, the Qingming Festival, observe the wheat seedlings, if the growth is vigorous and do not top dressing, if you can't keep up with the large area of ordinary wheat seedlings can be top dressing once, after the rain an acre of urea 10 to 15 catties.

The average temperature of 6 degrees Celsius is the right temperature for spraying wheat fields. The average temperature of 6 degrees Celsius is the right temperature for spraying wheat fields. It is also necessary to combine the growth of wheat and the amount of weeds to choose the appropriate spray in time.

Chemical weeding spraying in wheat fields should be carried out in sunny and windless weather with a temperature of more than 6 degrees.

The appropriate temperature for wheat weeding should be above the average daily temperature6. When weeding wheat, it is necessary to observe the temperature and humidity, the average temperature should be higher than 6, it is more appropriate to be around 10 a.m. to 3 p.m., and when the soil is relatively dry, it is necessary to increase the amount of water, and there can be no stagnant water during the period, which will affect the efficacy of the herbicide is not good.

Wheat characteristics

Wheat semi-winter, multi-spike, early-maturing new varieties, seedlings creeping, narrow leaves, strong tillering ability, good wintering resistance, late spring up, fast polarization, early heading, with other semi-winter varieties difficult to compare with the advantages of early maturity. Xinong 979 had strong tillering power, high panicle formation rate, medium to large spike type, and the three elements of yield were coordinated.

The average yield per mu in the national and regional trials is 680 kg. The grain is large and full, bright and transparent, full of, and has a good appearance of commerciality. After years of multi-point sampling and analysis by the state, the protein content is 14 to 16%, the wet gluten is 32 to 34%, the sedimentation value is about one, the stability time is minutes, and the quality meets the national standard of high-quality strong gluten wheat.

It has become the preferred variety for the delivery of high-quality strong gluten wheat on the Zhengzhou Commodity Exchange. The plant height is about 75 cm, the stem elasticity is good, the lodging resistance is strong, the high and medium fertilizer can be planted, the high resistance to stripe rust, the medium resistance to scab, the medium susceptibility to sheath blight, powdery mildew, the comprehensive resistance is good, the adaptation range is wide, and the promotion and planting performance in the vast Huanghuai wheat area is outstanding.
