Which fertilizers are suitable for growing fertilizer

Now it is the period of crop sowing, when crops are sown, the application of seed fertilizer is of great benefit to seed germination and seedling growth. at present, seed fertilizer is applied in many areas. However, the variety of fertilizer is also more fastidious, not all fertilizers can be used as fertilizer, if you choose the wrong fertilizer, not only will not promote seed germination, but also may cause rotten seeds and dead seedlings. So what kind of fertilizer is suitable for growing fertilizer? Let's take a look at it after work.

1. Calcium superphosphate

Commonly known as common superphosphate, referred to as calcium superphosphate, it is suitable for a variety of crops and soils, mainly used as base fertilizer or seed fertilizer, which can reduce the fixation of phosphorus in soil and contribute to the absorption of phosphorus by seedlings. When making seed fertilizer, it is best to crush it, sift it, and then mix it with high-quality organic fertilizer and use it evenly. The purpose of this is to burn seedlings in order to have direct contact with the seed. It is appropriate to use 5-10 kg in general, 10-20 kg per mu if applied in time, and 20-30 kg per mu if spread.

2. Ammonium sulfate

Ammonium sulfate is referred to as ammonium sulfate, which is suitable for all kinds of crops. it can be used as topdressing and seed fertilizer. as seed fertilizer, excessive contact between ammonium sulfate and seeds should be avoided as far as possible. during application, both seeds and ammonium sulfate should be kept dry. General consumption per mu is 2.5 kg, can be mixed with sowing, not for a long time.

3. Heavy superphosphate

Heavy superphosphate is referred to as heavy calcium, when it is used as a kind of fertilizer, the application rate is about 2.5-5 kg per mu, because it does not contain calcium sulfate, so it is not as effective as superphosphate as a fertilizer for sulfur. In addition, the effect of its application in alkaline soil is not as good as that of calcium, which should be paid attention to.

4. Diammonium phosphate

Diammonium phosphate can be used as base fertilizer, or seed fertilizer and topdressing fertilizer, among which the effect of base fertilizer and seed fertilizer is the best. When using diammonium phosphate as seed fertilizer, it is best not to use too much, 2.5-5 kg per mu, and pay attention to isolation from seeds to avoid burning seeds and seedlings. Seed soaking can also be taken, with 2% diammonium phosphate solution, that is, 1 kg diammonium phosphate dissolved in 50 kg of water, soaked in 50 kg of corn for 24 hours, and then sowed after soaking slightly dry.
