After the zucchini is sitting on the melon, the plant transitions from vegetative growth to reproductive growth. The enlargement of the fruit needs to absorb a large amount of nutrients, compete for the nutrients needed for the growth of the plants, and in order to ensure that the vegetative growth and the reproductive growth are synchronized, the fertilization is required at this time. However, fattening can not be blind, first of all, according to the soil fertility, a simple understanding should be based on the use of base fertilizers for farmers to carry out fertilizer. Pay attention to the following two points:
The base fertilizer is mainly manure and organic fertilizer. However, the chemical fertilizers are used less frequently or are not to be noticed by the following: 1. Due to the less use of chemical fertilizers, the available fertilizers can be used as appropriate to avoid affecting fruit growth; 2. The first flush can be appropriately increased. The amount of fertilizer should be matched with a suitable compound fertilizer with a longer fertilizer effect. Generally, high-potassium compound fertilizer can be used for 10 to 15 kilograms of mixed organic fertilization and 30 to 40 kilograms per mu. 3. It is possible to shorten the period of flushing and fertilization, so as to avoid the phenomenon of premature decay of zucchini. 4. The selected red fertilization can be selected from amino acids, humic acid, and yellow humic acid, but the low nitrogen and high potassium type should be selected, and hormone-free, to prevent premature aging.
The manure, organic fertilizer and chemical fertilizer in the base fertilizer should be used with sufficient balance. Attention should be paid to the following: 1. Fertilizer shall be applied in a timely manner. According to the characteristics of the fertilizer required in each growth period of the crop, fertilizer shall be applied in time so as not to affect the normal growth of the fruit. 2. Appropriate amount of fertilizer To prevent excess fertilizer, it is advisable to apply 30-40 kg of organic fertilizer per mu; 3. Low nitrogen and high potassium fertilizer is the most suitable.
