It is particularly important to increase the quality of wheat sown when the frost falls.
Today, we will follow Professor Li Jincai, an expert in wheat cultivation at Anhui Agricultural University. Let's take a look at how we can improve the quality of wheat sown and make it safe for winter wheat to achieve high yields.
Due to the special temperature and weather this year, the sowing time has come and the germination rate has decreased, so we must increase the seeding rate. Especially in the northern Jianghuai and Huaihe River, the japonica rice and japonica rice should be quickly grabbed and then quickly prepared for wheat.
Wheat sowing generally follows the "Three Fifteen Principles":
1: Protect 150,000 basic seedlings;
2: The temperature is about 15 degrees;
3: Before and after the 15th: sowing.
For the sowing amount of wheat
How to control it?
The main considerations are as follows:
1: First of all, we must consider the selection of wheat varieties. It is best to choose the semi-winter varieties. If it is spring varieties, we must increase the sowing rate.
2: Considering the amount of wheat sown according to the land conditions, this is beneficial to the cultivation of strong seedlings, safe wintering and high yield;
3: According to the sowing method, if it is machine broadcast, it can be relatively less. If it is broadcast, especially if the land is wet, the sowing amount will increase.
4: The germination rate this year is between 70% and 80%. We must pay special attention to it. Early broadcast to reduce the amount of broadcast, late broadcast will increase the amount of sowing, seeding control should not exceed 50 pounds, in 30 pounds ~ 35 pounds or so;
5: Remember to avoid rotten root rotten species, can wait for the soil moisture conditions have improved and then sowing, every delay of one day, need to increase the amount of seed of half a catty;
6: At the stage of wheat sowing, it is important to remember that the sowing cannot be too deep so as to avoid causing weak seedlings.
