Embodiment Construction

[0008] A method to prevent rice from sitting or stiff seedlings is mainly to apply zinc fertilizer during the growth period of rice by the common methods of basal fertilizer, topdressing, foliar spraying, seed soaking, and seed dressing. The zinc fertilizer can be agricultural zinc sulfate. such as:

[0009] 1. Apply basic fertilizer, about 1.5 kg of zinc fertilizer per mu, and apply it when the land is cultivated;

[0010] 2. Foliar spraying, spraying once at the seedling stage and tillering stage of rice, 50 kg of 0.1-0.3% zinc sulfate solution per mu each time, can effectively prevent the "stuffy" and "stiff seedlings" of rice caused by zinc deficiency .

[0011] Spraying the above dose of zinc fertilizer during the fouling period can also increase the seed setting rate of rice. The records of many experiments show that if the zinc fertilizer is sprayed three times in the rice lifetime, it can increase the rice yield by about 10%.

[0012] In 2008, 68 households in Huaiyuan Coun...

Abstract

The invention discloses a method for preventing rice stifle or runt seedling, which is characterized in that: a zinc fertilizer is applied in the growth period of rice by using common methods, such as base fertilizer application, top application, leaf spray, seed soaking and seed dressing. The method can promote the breath and carbohydrate metabolism of the somatic cell of rice effectively, increase the utilization rate of oxygen, prevents rice stifle or runt seedling and realize yield and income.

Description

Technical field [0001] The invention belongs to a method for preventing plant diseases, in particular to a method for preventing rice sativa or rigid seedlings. Background technique [0002] The long-term waterlogging paddy field belongs to the gley-type paddy soil, which has strong reducing conditions, which inhibits the absorption of zinc by the rice roots, which is likely to cause the rice to be physiologically zinc-deficient, and the symptoms are mostly "stuffed" and "stiff seedlings". . There are many products on the market that prevent rice stubbornness or rigid seedlings, most of which are composite products. In the rice production process, the same or multiple substances are often not lacking. The excess elements will also affect the healthy growth of rice. Summary of the invention [0003] The purpose of the present invention is to provide a method for sitting or stiff seedlings of rice, which can effectively prevent the occurrence of the phenomenon of sitting or stiff s...
