In the process of vegetable planting, from the selection of soil properties, seed quality selection to sowing, germination, maturity, in the later stages of fertilization, the use of chemical fertilizers, watering and cold protection, etc., these are gradually step by step in order, therefore For the management of vegetables, some principle problems cannot be replaced alternately. For example, the use of organic fertilizers and fertilizers, the order of watering and transplanting, the order of pest control and disease prevention, and the order of nutrient supply are not reversed.
1. Application sequence of organic fertilizer and chemical fertilizer
a. Based on organic fertilizer and supplemented by chemical fertilizers, vegetables can be of high quality and high yield.
b, organic fertilizer must be decomposed, unfertilized organic fertilizer such as chicken manure, with salt and pests, affecting crop growth.
2. The order of application of phosphorus and potassium
a, pay attention to the application of potassium fertilizer, rational application of nitrogen fertilizer, phosphate fertilizer, which is especially important after sitting on the melon (fruit);
b. Avoid partial application of diammonium phosphate;
c. Rationally apply biological fertilizer to regulate nutrient supply.
3, the order of watering and transplanting
If the organic fertilizer is first sprinkled in the greenhouse, and then the fertilizer is applied, it will easily cause the roots of the seedlings to lose water, which may easily cause root burning or ammonia poisoning.
If water is first watered, the fertilizer will not easily burn roots and gas after it has been dissolved and diluted by water. Therefore, it is recommended to first water the sputum, then plant the seedlings, and then use the amino acid, humic acid fertilizer solution to fill the roots, pay attention to 7 to 10 days of irrigation, and even irrigation 3 to 4 times.
4, prevention of pests, nutrition regulation and watering sequence
If watering first, it will lead to overnutrition of vegetables and unhealthy growth. The quality of the harvested vegetables is not so good. On the other hand, it is easy to make the nearby environment more humid, which will lead to mildew and increase disease. Probability, so it is best to use watering and fertilizing vegetables before using disease prevention and pest control.
The above is the correct sequence of vegetable growing techniques. It is best to plant them according to these sequences during the planting process. Don't idle and exchange these orders. The reason why planting vegetables has its planting order is definitely the reason for it. Just follow it.
