Strawberry fertilizing method with growth promotion, quality improvement, effect increase and disease prevention functions

Abstract

A strawberry fertilizing method with growth promotion, quality improvement, effect increase and disease prevention functions comprises: a basal dressing and a top dressing, wherein the top dressing is divided into a soil top dressing and a plant top dressing, and wherein the basal dressing comprises mixing an organic fertilizer, a multi-element nutrient active material and a compound fertilizer, uniformly spreading the fertilizer mixture over fields with the amount of 1000 kg per mu, and performing rotary tillage with the tillage depth of 30 cm to mix soil and the fertilizer mixture uniformly; ridging with a height of 30 cm; about 1 month after transplanting strawberry plants and before covering tents, topdressing with the compound fertilizer of 10-15 kg per mu, and simultaneously performing foliar fertilization with a multi-element plant nutrient foliar fertilizer for one time with the amount of 50 kg per mu; before blooming, topdressing with the compound fertilizer of 10 to 15 kg per mu, and simultaneously spraying 50 kg of a high-nitrogen foliar fertilizer to the strawberry plants for one time; at the peak of strawberry blooming period and the peak of fruiting period, spraying the multi-element plant nutrient foliar fertilizer for one time with the amount of 50 kg per mu; in a fruit enlargement period, topdressing with the compound fertilizer of 10-15 kg per mu, and simultaneously spraying 50 kg of a high-potassium foliar fertilizer to the strawberry plants for one time; and later on, spraying with the multi-element plant nutrition foliar fertilizer for one time, every time after harvest.

Description

technical field [0001] The invention is a fertilization method that can promote the growth of strawberries, improve the quality and prevent diseases, and can be used to overcome the obstacle of continuous cropping of strawberries. Background technique [0002] Strawberry has high nutritional value, short production cycle and good economic benefits. Many farmers like to plant it. At present, in the protected cultivation of strawberries, due to the high-intensity use of soil and the large or even excessive fertilization that does not match the new crop varieties, serious health problems have occurred in many cultivated land soils. It is manifested as the accumulation of a large number of elements and the lack of medium and trace elements, resulting in the imbalance of soil nutrients and the decline of soil nutrient conversion ability. At the same time, under the conditions of high nutrient imbalance and soil quality deterioration, the ability of plant roots to grow and absorb...

AI Technical Summary

Problems solved by technology

At present, in the protected cultivation of strawberries, due to the high-intensity use of soil and the large or even excessive fertilization that does not match the new crop varieties, serious health problems have occurred in the soil of many cultivated lands.

It is manifested as the accumulation of a large number of elements and the lack of medium and trace elements, resulting in the imbalance of soil nutrients and the decline of soil nutrient conversion ability

At the same time, under the conditions of highly unbalanced nutrient levels and deteriorating soil quality, the ability of plant roots to grow and absorb water and nutrients will drop sharply, leading to problems in plant health, and decline in resistance to diseases, insect pests and other adversities
