Vegetables in plastic sheds should pay attention to scientific fertilization

Plastic pipe sheds and other protection facilities are a relatively closed environment, especially in the winter stage, the outside temperature is low, in order to maintain the temperature inside the pipe shed, generally less ventilation, so if the method of topdressing is not appropriate, it is easy to cause fat damage.

1, vegetable eggplant melon seed bed fertilizer

Vegetable seedbeds generally use farmyard manure as the base fertilizer. If pigs, ducks, etc. are used as base fertilizer, they must be fully decomposed before they can be applied. It is to use commercial organic fertilizer, and it should be applied to the soil 10-15 days in advance. Fermentation in the soil, and then sowing or raking, can not be planted or raked after the application of organic fertilizer on the same day, which is conducive to increase the emergence rate and prevent rooting.

2, after the application of ammonium bicarbonate in the shed, pay attention to deep application

Ammonium bicarbonate is easy to absorb moisture and decompose, and volatilizes a large amount of ammonia gas after being applied in the shed. When the ammonia gas reaches a certain concentration, it is unfavorable for the growth of vegetables. Therefore, deep application (10 cm into the soil) should be paid attention to when topdressing, and then the soil is covered. It can prevent the loss of fertilizer volatilization and prevent burning of vegetable crops.
