Embodiment 1

[0019] Chinese cabbage was selected to carry out foliar fertilization experiments in Suzhou Facility Vegetable Cultivation Base. Before planting vegetables, mix organic fertilizer and compound fertilizer evenly according to the mass ratio of 95%:5%, and sprinkle them into the soil when preparing the ground, with an amount of 300 kg per mu. Among them, the N-P of compound fertilizer 2 o 5 -K 2 O is 15%-15%-15%, the nutrient content of organic fertilizer is greater than 3%, and the organic matter content is greater than 30%. After the fertilizer is applied to the soil, turn the ground and select seedlings of appropriate size for planting. Liquid surface topdressing was carried out four times during the entire growth period of vegetable growth. Among them, spray fertilizer once at the seedling stage, with an amount of 30 kg per mu. The fertilizer used is Tianquan brand plant nutrient liquid fertilizer (developed by the Institute of Oceanology, Chinese Academy of Sciences, pat...

[0026] Cabbage was selected to carry out foliar fertilization experiments in Suzhou Facility Vegetable Cultivation Base. Before planting vegetables, mix organic fertilizer and compound fertilizer evenly according to the mass ratio of 95%:5%, and sprinkle them into the soil when preparing the ground, with an amount of 300 kg per mu. Among them, the N-P of compound fertilizer 2 o 5 -K 2 O is 15%-15%-15%, the nutrient content of organic fertilizer is greater than 3%, and the organic matter content is greater than 30%. After the fertilizer is applied to the soil, turn the ground and select seedlings of appropriate size for planting. Liquid surface topdressing was carried out four times during the entire growth period of vegetable growth. Among them, spray fertilizer once at the seedling stage, with an amount of 25 kg per mu. The fertilizer used is Tianquan brand plant nutrient liquid fertilizer (developed by the Institute of Oceanology, Chinese Academy of Sciences, patent numb...

Embodiment 3

[0030] Cauliflower was selected for foliar fertilization experiments in Suzhou Facility Vegetable Cultivation Base. Before the cauliflower is planted, mix the organic fertilizer and compound fertilizer evenly according to the mass ratio of 95%: 5%, and sprinkle it into the soil when preparing the ground, with an amount of 300 kg per mu. Among them, the N-P of compound fertilizer 2 o 5 -K 2 O is 15%-15%-15%, the nutrient content of organic fertilizer is greater than 3%, and the organic matter content is greater than 30%. After the fertilizer is applied to the soil, turn the ground and select seedlings of appropriate size for planting. Four times of foliar topdressing were carried out throughout the growth period of vegetable growth. Among them, spray fertilizer once at the seedling stage, with an amount of 40 kg per mu. The fertilizer used is Tianquan brand plant nutrient liquid fertilizer (developed by the Institute of Oceanology, Chinese Academy of Sciences, patent number...

Abstract

The invention provides a foliar topdressing method for promoting yield increase of heading leaf vegetables under protected cultivation conditions. The method is characterized in that base fertilizer is distributed and applied to soil during soil preparation, wherein the base fertilizer is a mixture of organic fertilizer and compound fertilizer which are in a mass ratio of 95%:5%; and foliar fertilization is carried out four times in the whole growth periods of the leaf vegetables as follows: tiller fertilizer is sprayed once in the seedling period, rosette fertilizer is sprayed once in the rosette period, heading fertilizer is sprayed once in the heading period and relay fertilizer is sprayed again in the medium heading period, wherein the tiller fertilizer and the relay fertilizer are multielement plant nutrient foliar fertilizers, the rosette fertilizer is high nitrogen foliar fertilizer and the heading fertilizer is high potassium foliar fertilizer. The experiments design the fertilization scheme specially for the heading leaf vegetables under high temperature and high humidity protected cultivation conditions in the south but not for open or other leaf vegetables and have strong pertinence. By adopting the method, the yield of the cabbages can be increased by over 30%, the yields of Chinese cabbages and broccolis are increased by over 40%, the vegetable quality can be obviously improved and the farmer income can be increased.

Description

[0001] technical field [0002] The invention belongs to the technical field of high-efficiency agriculture, and in particular relates to a foliar fertilization method for increasing the yield of head-heading leafy vegetables under facility cultivation. [0003] Background technique [0004] With the development of social economy, the consumption of vegetables is increasing day by day, coupled with profit-driven reasons, the number of farmers engaged in vegetable production is also increasing. The industrialized production of vegetables has led to the emergence of a number of characteristic large-scale professional production areas in various parts of our country. Leafy vegetables are one of the essential foods in people's daily diet. It not only provides a variety of vitamins and minerals necessary for the human body, but also has a variety of phytochemical components that are effective for health, which can prevent various diseases to a certain extent. Heading leaves r...
