Pitaya water and fertilizer integrated fertilization planting method based on LED light supplementing and flower forcing

Abstract

The invention discloses a pitaya water and fertilizer integrated fertilization planting method based on LED light supplementing and flower forcing. The pitaya water and fertilizer integrated fertilization planting method comprises the steps that different fertilizer formulas are adopted for irrigation in different flowering periods, the fertilizer is irrigated along with water, and a tricyclic 18-18-18-boron-containing fertilizer mixed with mineral source chelated nine-element fertilizer and mineral source humic acid is adopted in a spring shoot germination period; a fertilizer formed by mixing monopotassium phosphate, tricyclic 18-18-18-boron-containing mineral source chelated nine-element fertilizer is adopted in the early flowering stage; in the flowering stage and the young fruit stage, a fertilizer formed by mixing monoammonium phosphate, tricyclic 18-18-18-boron-containing fertilizer and organic water-soluble fertilizer is adopted; in the fruit strengthening period, a fertilizer formed by mixing potassium nitrate, calcium magnesium nitrate and an organic water-soluble fertilizer is adopted; and in the flowering and fruiting period, a fertilizer formed by mixing Hengshui Lake 17-17-17 nitro-sulfenyl, natural potassium magnesium sulfate or mineral source chelated nine-element fertilizer and organic water-soluble fertilizer is adopted. According to the pitaya water and fertilizer integrated fertilization planting method based on LED light supplementing and flower forcing, it is ensured that water and fertilizer applied in each stage can be utilized timely and efficiently.

Description

technical field [0001] The invention relates to the technical field of agricultural planting, in particular to a method for fertilizing and planting dragon fruit integrated with water and fertilizer based on LED supplementary light and flower urging. Background technique [0002] Dragon fruit belongs to the cactus family. Its fruit tastes sweet, rich in nutrition, and has health functions such as anti-oxidation. In recent years, my country's Guangdong, Guangxi, Hainan and other provinces have vigorously developed planting, which has good economic benefits and is favored by fruit farmers. Dragon fruit is a long-day plant, and the critical day length is about 12 hours. The annual production period is basically concentrated from June to December. In spring and winter, it is difficult to reach the light compensation point and light saturation point of dragon fruit due to the number of hours and intensity of light. Therefore, fruit trees will enter a dormant period, which direct...

Problems solved by technology

Therefore, special attention should be paid to the fertilization of dragon fruit, too much can easily cause root damage

At the same time, dragon fruit consumes a lot of nutrients during the growth period and flowering period, and has a large demand for fertilizers. However, in the traditional cultivation and management of dragon fruit, irrigation and fertilization are carried out separately, and the coordination of water and fertilizer has not been fully exerted, resulting in a considerable part of fertilizer being applied to the soil. After that, it is not absorbed by the fruit trees, the fertilizer utilization rate is low, and resources are wasted. At the same time, there are problems of high labor intensity and low efficiency.
