Wheat sowing adjustment methods and precautions, scientific guidance for improving yield
The amount of wheat planted per hectare must be adjusted on a case-by-case basis, and may increase or decrease depending on the variety and soil conditions. Commonly used production tests"500 grams and 10,000 seedlings"However, this is only a guideline value, and the specific amount of wheat seeds must be calculated according to the actual situation.
In general, the best time to sow wheat is from October 5 to 20, and sowing too early or too late can affect yields. The suitable density is 1 million to 1.5 million holes per hectare, and the specific sowing amount should be adjusted according to the actual situation. Under the conditions of appropriate early sowing, the sowing rate per mu is 75-10 kg in high-yield fields, 10-125 kg per mu in general fields, and 125-15 kg in late-sown wheat fields.
Wheat yield is composed of three parts: spike number, grain number per spike and grain weight, and the basic seedling number is the basis for reasonable dense planting. To determine the sowing amount of wheat, it is necessary to consider factors such as wheat yield composition, basic seedling number, soil fertility, variety characteristics, and sowing date. Therefore, farmers should determine the sowing amount according to the actual situation to get the best growth effect.
