The application of organic fertilizers and chemical fertilizers cannot be reversed. First, organic fertilizers are mainly used, supplemented by chemical fertilizers, so that high quality and high yields of vegetables can be produced without pollution. Followed by organic fertilizer must be cooked. After the application of unprocessed organic fertilizer, human and financial resources must also be spent to prevent pests and diseases.
The application of phosphorus and potassium can not be reversed in the production process of fruits and vegetables. In addition to the three major elements of carbon, hydrogen and oxygen, nitrogen is the key to the formation of plants. Phosphorus and potassium are the main elements of fruit formation. According to relevant information, the ratio of phosphorus and potassium in the formation factors of melon vegetable production is 1:2-1:3, and the utilization rate is 20%-30% and 50%-70%, respectively. Therefore, in the fertilization process, we must pay attention to the application of more potassium fertilizer, a reasonable allocation of nitrogen fertilizer, phosphate fertilizer, which is particularly important after sitting on fruits. In the past, the love of partial diammonium phosphate must be avoided. And rational use of biological fertilizers to regulate nutrient supply.
The order of preventing and controlling pests and watering and fertilizing cannot be reversed. It is necessary to first use drugs to prevent pests and diseases, first use inhibitors, regulate growth potential, and then water and fertilize, so as to avoid self-contradictory problems and increase production.
Water-planting and transplanting planting can not be turned upside down in some areas. There have been mistakes in water-planting and vegetable transplanting, resulting in dead seedlings. Nowadays, many vegetable farmers spread organic fertilizers in the sheds, fertilize them with fertilizers, and then plow them. After leveling, they plant the vegetable seedlings by ridging and then water them. This process leaves the seedlings with water loss in the root system, which can easily lead to burning of roots due to contact with fertilizers, or cause ammonia poisoning. If the water is first applied, the fertilizer is not easily regenerated by the dissolution and dilution of water, and it is not easy to produce gas. Therefore, it is recommended that water should be used to make oysters, then plant seedlings, then use amino acid humic acid fertilizer to irrigate the roots, pay attention to 7-10 days irrigation once, and even irrigation 3-4 times.
