In recent years, Laizhou City has vigorously implemented the greenhouse industry project focusing on the production of vegetables and vegetables, and the rapid development of the melon and vegetable industry in Laizhou, and the establishment of projects in science and technology demonstration counties have provided favorable conditions for farmers. Whether vegetables can increase production, how fertilization is the key. The practical experience of vegetable farmers is: To "see the sky, see the fields, see the vegetables," fertilize the "see the sky" fertilization: that is, no fertilizer in the rain, so as not to lose fertilizer. Days of nausea are not applied, the fog is not applied, the temperature is not applied, so as not to cause the disease of rotten plants, fertilization should be selected sunny.
"Look at the place" fertilization: that is, a good soil quality and less applied, the soil quality is poor. Excessively hardened, hard-to-prepare organic fertilizers, etc., should be properly applied, and should be applied sparingly, thinly, repeatedly, and in small quantities. In addition, different soil qualities and fertilization methods are also different. The light loam soil pellet structure has good fertilizer and fertilizer performance, and can be applied and reused. The sandy loam was used less frequently to prevent fertilizer waste.
"Look at the vegetables" Fertilization: To understand how to identify which fertilizer is lacking in vegetables. There are rhizobium-fixing nitrogen in the bean type, requiring less nitrogen and more phosphorus; root vegetables and yams need more potassium; leafy vegetables only need more nitrogen; fruits and vegetables are based on sufficient nitrogen fertilizer. Need to use phosphorus and potash fertilizers.
