How many kilograms of seeds are suitable for growing wheat in the field? What should I pay attention to? According to my years of planting experience, there are the following points to pay attention to, depending on the planting time. If it is in the suitable period (usually 65438+1October 5-20), the more wheat seeds are used, the less the dosage is, and the dosage can be appropriately increased in the later period of the suitable period. According to the tillering ability of wheat seeds, varieties with strong tillering ability can use less seeds, on the contrary, it is more appropriate to use a few kilograms. It depends on the temperature. If the weather forecast is that the temperature will be high for a period of time after planting wheat, sow less; if the temperature is lower than normal, sow more appropriately.

It depends on what crops are planted in the previous crop. If it is a soybean or vegetable crop, this kind of plot can be cultivated with less seeds. If it is a tall crop with more stubble such as corn, it is necessary to use more seeds appropriately. It depends on the soil quality. If the soil is loose, wheat seeds with good coverage and high germination rate can be used less. If the soil is as hard as red soil, it is easy to appear soil after rotary tillage, which is not conducive to seedling raising. We must use more seeds. Take Xinxiang, Henan Province as an example. Generally, conventional varieties use 25 kilograms of wheat seeds in the early stage of maturity and 30 kilograms of wheat seeds in the late stage of maturity. (Of course, if the soil is hard and the soil moisture is not good, it is ok to use 35 to 40 kilograms. After maturity, the amount of seeds will increase by one catty every three days, up to 50 catties. The key is to use it flexibly according to local conditions. Of course, there is also the fertility of the land, and the fertilizer should be thin and thick.

How many kilograms of seeds are suitable for planting is a problem of close planting. From the production practice, dense planting is not good, and sparse planting will not produce high yield. That is, reasonable close planting, because reasonable close planting can make full use of soil fertility and sunlight, produce more nutrients, promote wheat growth, make the population reasonable, not only grow more ears, but also resist lodging, and finally achieve the goal of high yield. According to the current production level and scientific and technological level, the yield is mainly improved by heading the main stem, that is, the yield is 400,000-500,000 ears per mu, and the basic seedlings must be 20-25, so that each plant has more than one tiller, so that the yield of seeds per mu is about 20 kg. This is the general situation, and the sowing amount depends on soil fertility, stubble and other factors. For example, if the land is fertile and the crop is early, the sowing amount should be around 18 kg. If the soil fertility is poor and it is late-cropping wheat, the sowing amount should be about 25 kg. In addition, the tillering characteristics of the varieties used should be considered. Those with strong tillering ability should reduce the normal sowing amount 15%, win with more tillers, and strive for 3-4 tillers per plant and enough groups before the year. On the contrary, it increased 15%, and many main stems formed spikes, reducing the appearance of ineffective tillers.
