Base fertilizer capable of preventing cotton anthracnose

Abstract

The invention relates to a base fertilizer capable of preventing cotton anthracnose. The base fertilizer capable of preventing the cotton anthracnose is prepared by inoculating penicillium in a conventional base fertilizer and simultaneously adding an alkaline copper sulfate solution; the penicillium can be used for killing colletotrichum but also can eb used for killing a plurality of beneficial bacteria in soil, so that based on research carried out for years and by reasonably controlling the inoculation amount of the penicillium in the base fertilizer, the base fertilizer capable of preventing the cotton anthracnose can be used for restraining the propagation growth of the colletotrichum, and can be used for thoroughly and effectively killing the colletotrichum by using the alkaline copper sulfate solution.

Description

technical field [0001] The invention relates to the field of crop fertilizers, in particular to a base fertilizer capable of preventing cotton anthracnose. Background technique [0002] Cotton cultivation first appeared in the Indus Valley Civilization in the 5th to 4th millennium BC. Before the Common Era, the use of cotton textiles spread to the Mediterranean region. In the first century AD, Arab merchants brought fine cotton cloth to Italy and Spain. [0003] In the 9th century, Arab traveler Suleiman described in his "Suleiman's Travel Notes" that cotton was seen in China and was viewed as a "flower" in the garden. Grass is like a cocoon, and the silk in the cocoon is like a thin silk. It is called Baidiezi. The earliest cotton textile relic found in the Central Plains is a cotton blanket found in an ancient tomb in the Southern Song Dynasty. In the early Yuan Dynasty, the imperial court made cotton cloth As the head of the summer tax (cloth, silk, silk, cotton), the ka...

Problems solved by technology

[0004] my country is the country with the largest cotton yield in the world. It is widely planted in the Jianghuai Plain, Jianghan Plain, southern Xinjiang cotton area, central Hebei, southern Shandong, northwest Henan, and the lower reaches of the Yangtze River along the coast. However, the annual production reduction due to diseases is 15 %-20%, among which the impact of anthrax is particularly prominent, the existing technology often waits until after the onset of drug treatment, and in many cases the treatment effect is not good
