Method for preventing and controlling tomato blossom-end rot and fruit cracking by using improved particle lime nitrogen and application of improved particle lime nitrogen

Abstract

The invention discloses a method for preventing and controlling tomato blossom-end rot and fruit cracking by using improved particle lime nitrogen and application of the improved particle lime nitrogen. The improved particle lime nitrogen is prepared from the following components in percentage by mass: 0.47 to 1.4% of silicon, 7.17 to 11.41% of oxygen, 18.3 to 24.33% of carbon, 0.53 to 1.59% of aluminum, 39.34 to 50.26% of calcium, 0.14 to 0.7% of iron, 0.18 to 0.6% of magnesium and 18.46 to 23.01% of nitrogen. The method comprises the following steps: during soil preparation, spreading an organic fertilizer or animal manure, spreading the improved particle lime nitrogen, turning over, bedding, sealing, irrigating water in a bed, removing a film, airing, and the like; ventilating air for airing, and transplanting a tomato seedling; dressing a compound mixed fertilizer for three times in the growth process of the tomato seedling after transplanting. The improved particle lime nitrogen has the advantages that the good promoting function on the growth of tomato is realized, the botrytis and blossom-end rot of the tomato can be effectively prevented and controlled, and the commodity property of the tomato is improved; the obstacle of continuous cropping of soil is prevented, and the soil property is improved; by using the improved particle lime, the output of the tomato is obviously increased, the rate of growth reaches 9.01%, the economic benefit is obvious, and the input-output ratio is 2:1.

Description

technical field [0001] The invention relates to the field of agriculture, in particular to a method and application of improved granular lime nitrogen for preventing and treating navel rot and fruit cracking of tomatoes. Background technique [0002] Tomato, also known as tomato, is rich in nutrition and has a special flavor. It has the effects of losing weight, eliminating fatigue, increasing appetite, improving protein digestion, and reducing bloating and food accumulation. Tomatoes are prone to navel rot and fruit cracking during the cultivation process. [0003] Tomato navel rot, also known as pedicle rot, is one of the most common diseases on tomatoes. Severe disease often causes fruit black spots and rot, which directly affects yield and quality. The disease is a physiological disease caused by water supply imbalance, calcium deficiency, boron deficiency and other reasons. Generally, after the first fruit ear is set, the plant is in a vigorous growth stage. In cas...

AI Technical Summary

Problems solved by technology

The reasons for fruit cracking are firstly due to deformed flowers; secondly, due to strong light exposure, high temperature and drought in the later stage of fruit development or color change period, especially after a long drought, it is easy to cause the growth of fruit skin and the expansion of flesh tissue The speed is not synchronized, and the turgor pressure increases, resulting in cracked fruit; the third is the improper use of plant growth regulators, the concentration is too high when using, and the water and fertilizer cannot keep up, causing physiological disorders and resulting in cracked fruit; the fourth is premature topping, resulting in concentrated supply of nutrients to the fruit cracking
