The base fertilizer of zucchini varies with different fertilizer.

After sitting, the plant transitions from vegetative growth to reproductive growth, and the expansion of the fruit needs to absorb a large amount of nutrients to compete for the nutrients needed for plant growth. In order to ensure the synchronization of vegetative growth and reproductive growth, it is necessary to flush fertilizer at this time. However, fertilizer can not be blind, first of all, according to soil fertility, simple understanding should be based on the use of vegetable farmers base fertilizer different and fertilizer. Attention should be paid to the following two points: The base fertilizer is mainly manure and organic fertilizer, and those who use less or even no chemical fertilizer should pay attention to: 1. Due to the use of less chemical fertilizer, quick-acting fertilizer can be appropriately applied to avoid affecting fruit growth;2. The amount of fertilizer for the first time can be appropriately increased, and it should be matched with appropriate compound fertilizer with longer fertilizer effect. Generally, 10~ 15kg of high-potassium compound fertilizer can be selected for each mu, and 30~ 40kg of organic fertilizer can be mixed;3. The application cycle can be shortened appropriately, and the fertilizer can be washed once more, so that the phenomenon of premature aging of zucchini will not occur;4. The selected fertilizer can be amino acid, humic acid, yellow humic acid, but low nitrogen and high potassium type, and does not contain hormones, to prevent premature aging. In the base manure, manure, organic fertilizer, chemical fertilizer use sufficient, balanced should pay attention to: 1. appropriate irrigation fertilizer, according to the fertilizer needs of each crop growth period characteristics, timely topdressing, so as not to affect the normal growth of fruits;2. appropriate irrigation fertilizer, prevent excessive fertilizer damage, with organic fertilizer per mu irrigation 30~40 kg is appropriate;3. low nitrogen high potassium fertilizer is the most appropriate.
