Soil amendment for inhibiting cracking of Xinjiang red dates, and preparation and using methods for soil amendment

Abstract

The invention discloses a soil amendment for inhibiting cracking of Xinjiang red dates. The soil amendment is prepared by mixing liquid fulvic acid, calcium nitrate, sucrose, potassium permanganate and citric acid. The product has a remarkable effect of preventing red dates from cracking, is characterized in that: after the product is used once, an effect can last for many years, and is suitable for controlling diseases such as serious cracking of red dates, shortage of organic matter, high salinity, unbalanced nutrition, nutrient deficiency and the like. The amendment can be taken as a base fertilizer or an additional fertilizer to be flushed with water or drip-irrigated to use, and can also be taken as a foliar fertilizer to be sprayed onto leaves in a growth period of the current year of the red dates or a diseased period of a cracking symptom of the red dates.

Description

technical field [0001] The invention relates to the field of soil improvement, in particular to a soil improver for inhibiting Xinjiang jujube fruit cracking and a preparation and use method thereof. Background technique [0002] Since the reform and opening up, Xinjiang's agricultural production has made great progress relying on national policy support and agricultural scientific and technological progress. It has become an important industrial belt of high-quality special forest and fruit products in the country, and has promoted the rapid development of Xinjiang's rural economy. In recent years, Xinjiang is gradually becoming the largest artificial intensive cultivation base of high-quality jujube in my country, and the jujube industry has become a new pillar industry of Xinjiang's economy. At present, the planting area of ​​jujube trees in Xinjiang has accounted for 50% of the total area of ​​horticultural crops, and the annual newly-increased area accounts for 50% of t...

AI Technical Summary

Problems solved by technology

However, while Xinjiang jujube trees have achieved large-scale development, there is a serious problem of fruit cracking: the fruit cracking rate of jujubes in southern Xinjiang is 15% in general years, and 50%-80% in rainy years during the mature period; for easy-cracking varieties, the fruit cracking rate in general years is 50% %-70%, up to 95% in severe years

Jujube fruit cracking seriously affects the quality of jujube, which leads to inconsistent commerciality and uneven quality of jujube, which is not suitable for the positioning of high-quality and high-grade jujube production base in Xinjiang
