Abstract

The invention relates to a drought-resistance type foliar fertilizer for wheat and a preparation method thereof. The drought-resistance type foliar fertilizer for wheat is prepared by adding starch and Tween into the main raw materials of amino acid, humic acid, an NPK fertilizer and / or trace elements. The fertilizer is used as the foliar fertilizer to be applied to the wheat, can improve the tillering capability and the drought and lodging resistance of the wheat, and has favorable effects on increasing the yield and improving the quality of the wheat.

Description

(1) Technical field [0001] The invention relates to a wheat foliar fertilizer with a drought-resistant function and a preparation method thereof, belonging to the technical field of agricultural fertilizers. (2) Background technology [0002] my country is a large agricultural country, and wheat occupies a very important position in agricultural production. China's wheat production and consumption have been around 100 million tons for many years, ranking first in the world. It is a major producer and consumer of wheat, and is also a major wheat trader in the world. Wheat is one of the main food crops in my country, and it is planted all over the country. In my country, the status of wheat is second only to rice. my country's winter wheat area accounts for more than 90% of the total wheat area, mainly distributed in the south of the Great Wall, the Yellow River, the Huaihe River and the Yangtze River in the east of the Minshan and Tanggula Mountains, including Henan, Shando...
