The invention discloses a kind of crop leaf covering agent including the following raw material components, according to weight: plant straw, lignite, clay and carbon powder. After comminution, the above ingredients are added to the mixer to be mixed evenly after packing, which is the finished product. The invention provides a foliar covering agent in the susceptible period of the crop, forming a uniform protective film on the surface of the leaf. The spores in the atmosphere will not directly fall to the surface of the leaf but fall on the cover agent. Because the pathogen does not directly contact the surface of the leaves, the pathogen will form a physical block, and the pathogen will not infect the leaves, because the disease is ill. The survival time of the original bacteria in vitro is 1 and 24 hours, and as time goes on, the susceptible period of the general crop to a certain kind of gas borne disease is 7 and 10 days. The invention has only 15 days to control the covering time of the inventive preparation, that is, it can effectively prevent the occurrence of a crop gas transmission disease. The invention has low cost and is easy to turn waste into treasure. Processing, no pollution, high efficiency.
【技术实现步骤摘要】
一种农作物叶片遮盖剂及其制备方法
本专利技术涉及农作物菌、虫防治
,具体涉及一种农作物叶片遮盖剂及其制备方法。
技术介绍
目前使用在农作物叶片喷施的制剂均是肥料或化学农药,肥料用于补充作物营养,化学农药用于叶片的杀菌和除虫,目前生产中,作物气传病害的防控仍然以喷施化学杀菌剂为唯一途径。杀菌剂的使用一方面污染生态环境、二来在作物上有农药残留,三则持效期短,需要在作物叶部病害易感期多次喷施,才能达到杀菌防病的效果,浪费人力、物力和财力,同时也对环境造成污染。由于一般作物对某一种传染病害的易感期在7-10天,通过喷施药物来防治气传病害的防效一般为65-70%,所以,农民盼望有一种更理想的办法来解决上述弊端。
技术实现思路
本专利技术的目的是提供一种农作物叶片遮盖剂,在作物易感期,喷施本专利技术制剂,在叶片表面形成一层均匀的保护膜,形成了物理阻断,使病原菌不能侵染叶片,对于气传病害的防效可以达到90%以上,本专利技术还公开了其制备方法。为了实现上述目的,本专利技术的技术方案是:一种农作物叶片遮盖剂包含下列原料组分,按重量为:植物秸秆70%褐煤17%粘土10%碳粉3%其制 ...
【技术保护点】
