Do not forget the soil test formula

When the soil samples must be properly sampled, they may be sampled in the “S” or “diagonal” manner. During actual operation, clean up the sampling tool and remove any plant debris or other debris from the sampling point. Then scrape off 2 to 3 cm thick topsoil at the sampling point, dig into an undamaged vertical section of less than 20 cm with a shovel, and then use a spade to take a 10 cm wide, 2 cm thick vertical soil. Use a knife to cut the soil into 2 cm wide, 2 cm thick, and 0 to 20 cm long top-down soil strips, spread out on a plastic sheet, and crush the large pieces. Seven to ten soil strips collected by the same method are mixed thoroughly to form a mixed sample. The mixture is paved into squares and diagonal lines are drawn. The soil sample is divided into four parts by “quaternary method”, and two diagonal copies are reserved. Repeatedly reduced to 0.5 kg into the sample bag for laboratory use.

When formulating the organic fertilizer, it must be applied to soil samples. After formula fertilization, we must pay attention to the application of organic fertilizer such as chicken manure and rice husk manure. This is the basis for guaranteeing high quality and high yield of vegetables. Under normal circumstances, solanaceous fruit Vegetables per acre shed should be based on chicken manure 15 to 20 cubic meters, rice husk manure 35 to 40 cubic meters, leafy vegetables per acre shed should be applied chicken manure 8 to 10 cubic meters, rice husk manure 15 cubic meters.

When you find that a certain element is lacking, don't make up for it. After measuring the abundance of nutrients in the soil, you should not find that a certain element is lacking and make a lot of “nuisances” because excessive fertilization will not only cause waste, but also cause fertilizer. harm. When basic fertilizer is applied, under normal circumstances, farmyard fertilizer should not exceed 50 kg, manure should not exceed 30 kg, and potassium fertilizer should not exceed 40 kg. If compound fertilizer is applied, it should not exceed 100 kg per mu.
