How many seeds, fertilizers, pesticides and plastic film should be used for one mu of soybeans?

Soybeans, commonly known as soybeans, leguminous soybeans are annual herbs, originated in China, are cultivated all over China, and are widely cultivated all over the world. So how many seeds, fertilizers, pesticides and plastic mulch do it generally use per mu? According to Sun Haijun, a soybean grower in Laiwu, Shandong Province, sowing per mu of soybeans is generally about 6 jin, which can be appropriately adjusted according to the situation, and the yield per mu is about 180-200 kg.

How much fertilizer does one mu of soybeans use?

The main results are as follows: 1. the general soybean is fertilized for the third generation of diamine per hectare, the first generation of potassium fertilizer and the first generation of large granular urea.

2. 400 kg of farm organic fertilizer, 36 kg of calcium magnesium phosphate fertilizer and 100 kg of urea should be applied to barren soil every 667 square meters.

3. When urea is used as foliar fertilizer in soybean fields, the concentration is 1%, the fertilizer spraying liquid is 30kg / mu, and urea is 300g / mu.

How many pesticides and plastic film should be used in one mu of soybeans?

There are usually instructions for the use of pesticides, such as 80-120g per mu, or 1000-2000 times of liquid, and so on.

In theory, the amount of water used for artificial spraying is about 60kg per mu, but in practical production, 2 pots of water, that is, 30kg, can be sprayed on one mu of land. At this time, if the dosage is 80g per mu, adding 40g pesticide per pot can ensure that the dosage per mu can reach 40g; if it is stated that it is 1000 times liquid, according to the theoretical calculation of water consumption per mu, 60g is needed, and 30g (that is, 500x liquid) is added to each pot in practical operation. When using agricultural machinery to drive high-pressure medicine pump to spray, the water consumption per mu will be less, as long as the pure drug quantity per mu can be ensured to meet the requirements.

Plastic film: the actual use of an acre of land is 666square meters. If the pet product is 12u thick, one ton is 59500 square meters. If 85kg is 20uopp, one ton is 55500 square meters, that is, 80kg.
