Can wheat sow at the same time?

China is one of the earliest wheat planting countries in the world, the development of wheat industry is directly related to national food security and social stability, sowing quality is related to the level of yield. So, can wheat sowing be sown with fertilizer?

1. Can wheat sowing be planted and fertilized simultaneously?

Wheat sowing can plant fertilizer and sow at the same time, but you should spread fertilizer and then sow seeds at the same time, not mixed sowing, and choose good varieties.

2. Matters needing attention in simultaneous sowing of wheat seed and fertilizer

1. Select superior varieties

At present, most of the no-tillage planters use large row and wide seedling belt, so try to choose wheat varieties with strong tillering ability and high panicle rate. The seeds should be carefully selected before sowing, requiring that the cleanliness of the seeds is not less than 98%, the purity is not less than 97%, and the germination rate is more than 95%. After seed selection, the seeds should be treated with drug dressing, seed soaking or coating to prevent the occurrence of diseases and insect pests.

two。 The sowing rate is appropriate

The sowing rate should be determined according to the tillering panicle rate and seed germination rate of the selected varieties, and whether the sowing rate is appropriate or not has a great influence on the yield. The reasonable sowing rate must be determined according to different soil conditions and sowing time. Generally speaking, wheat sown under no-tillage is about 10% more than that under conventional tillage. In the suitable sowing time, the tillering ability of large panicle type varieties is relatively weak, and the sowing rate should be 10-12 kg, while that of spikelet type varieties is relatively strong, and the sowing rate should be 7-8 kg. The seeding rate of each line of the planter should be the same, and the seeds should be dispersed evenly within the sowing range, and there is no missed rebroadcast.

3. Control the sowing depth and pay attention to the effect of suppression

The sowing depth should generally be controlled at about 3 cm, sandy soil and arid areas should be appropriately increased by 1-2 cm, the depth should be consistent, and the suppression should be dense. Inconsistent sowing depth or poor suppression effect will directly affect the uniformity of wheat emergence, which is not conducive to the cultivation of strong seedlings.

4. Pay attention to sowing with suitable soil moisture

Be sure to check the soil moisture before sowing so that it is suitable for sowing. The suitable moisture content of loam is 18% Mel 22%, and that of sandy soil is 19% Mel 20%. It is not suitable to sow seeds even if it is too wet or too dry. Otherwise, it will not only affect the seedling emergence effect, but also affect the early growth and development of wheat. No-tillage sowing wheat should not be irrigated immediately after sowing, one is to avoid thickening the soil cover, resulting in weak seedlings and reducing the tillering ability, and the other is to avoid the temperature being too low and affecting the tillering and rooting of wheat before winter, so that the population of wheat before winter is insufficient and the strong seedlings can not survive the winter.

5. Pay attention to the deep application of bottom fertilizer

For plots sown under no-tillage, do not spread chemical fertilizer, but apply it deeply when sowing. Base fertilizer to choose granular compound fertilizer, compound fertilizer or slow-release fertilizer, sowing rate of about 35 kg per mu, fertilization depth should be 5 cm below the side of the seed, try not to be in the same vertical plane as the seed. Base fertilizer can not choose quick-acting nitrogen fertilizer such as urea, ammonium hydrogen, etc., the amount of fertilizer application should not be too much, and the distance between kinds of fertilizer should not be too small, otherwise it is easy to cause "seed burning" or "seedling burning". After the sowing operation is completed, the fertilizer box, discharge pipe and fertilizer applicator must be cleaned so as not to damage the machinery and equipment parts.
