Abstract

The invention discloses a prevention solution for preharvest disease of Huping jujube and application thereof and discloses a fruit disease prevention solution. The provided fruit disease prevention solution contains mineral elements, chitosan and cryptococcus laurentii (Cryptococcus laurentii (Kuffer.) Skinner), wherein the mineral elements comprises the elements of calcium, boron, zinc and silicon; the ratio of the calcium to the boron to the zinc to the silicon to the chitosan to the cryptococcus laurentii (Cryptococcus laurentii (Kuffer.) Skinner) is (18.3-36.7g):(1.4-7.1g):(2.3-4.5g):(0.99-4.9g):(50-200g):(1*10<10>-1*10<12>CFU); and the calcium comes from organic calcium. According to the prevention solution, the amount of chemical pesticide and residual hazard of the pesticide on the fruits thereof are reduced, the prevention solution has the obvious effect of preventing the preharvest diseases of Huping jujube, and compared with the control group, the preharvest disease rate of Huping jujube can be reduced by 69.9 percent, and the prevention solution is convenient to use.

Description

technical field [0001] The invention relates to a liquid for preventing and controlling fruit diseases, in particular to a liquid for preventing and controlling jujube preharvest diseases and its application. Background technique [0002] Huping jujube is one of the top ten famous dates in my country. It is planted in large areas in Shanxi, Shaanxi, Xinjiang and other places, and plays a very important role in the agricultural production and life of local farmers. The cultivation area of ​​Huping jujube in Jinzhong area of ​​Shanxi alone exceeds 1 million mu, which is a pillar industry for the development of local agricultural economy. However, in recent years, preharvest diseases of Huping jujube fruit have become more and more serious, resulting in large area losses and yield reductions, which seriously affected the development of Huping jujube industry. The pre-harvest disease of Huping jujube fruit is mainly manifested as irregularly shaped black-red lesions on the top ...
