90% of the province's soil lacks boron, of which more than 70% of the area is seriously deficient in boron. The application of boron to crops has become an important technical measure in agricultural production. The new-type boron fertilizers, such as B-rich quick-acting boron fertilizers and boron-holding power, have the advantages of high boron content, good water-solubility, fast absorption rate, and easy absorption. They are applied to borax-sensitive crops such as rapeseed, cotton and peanuts, and the effect of increasing production and income is very obvious.
1. Based on the nutrition of crops such as rapeseed, cotton and peanut, and the characteristics of soil supplying boron, local conditions should be applied. Boron fertilizer should be applied to soils with soil available boron content below 0.8 mg/kg.
2, base fertilizer boron. Before sowing or transplanting crops, use 1 package (400 g) of boron fertilizer or 1 package (200 g) of boron for each acre with other fertilizers to mix and spread. . When boron fertilizer and chemical fertilizers are mixed together, the addition of fine organic fertilizers (usually 1:1 mixed organic fertilizers and chemical fertilizers) is beneficial to uniform application, and organic fertilizers can also function as protective films, and can also improve fertilizer efficiency. Basal application of boron fertilizer should be applied to the soil to reduce the loss of fertilizer efficiency.
3, spray boron fertilizer. During the rapeseed convulsions, cotton seedlings, early flowering stages, peanut seedling stage, flowering and needle stage, each foliar-fermented quick-acting boron fertilizer 1 package (50 g) is dissolved in 25 kg of water for foliar spraying. The leaves are moist and the water does not drip. The spraying time should be carried out in the sunny afternoon. If there is rain within 4 hours after spraying, it should be sprayed once.
4, attention. Avoid direct contact with crop seeds and roots so as not to affect seed germination and burn crop roots. Experiments show that the application of new types of boron fertilizer such as rich crown than the application of boron fertilizer per acre yield increase of 10 to 20%, 30 to 50 yuan per mu net income, production ratio of 1:5, improve fertilizer utilization 3 to 5 percentage points.
In 2006, 20 counties such as Wuxue, Zhashui, Huangmei, Ezhou, Daye, Anlu, Tianmen, Xiantao, Shayang, Fuyang, Nanxun and Hongan are planned to be used in the province's key rapeseed, cotton and peanut production areas. Demonstration 4 million mu. According to the yield increase of 15 kg of rapeseed and 10 kg of lint per mu, the province can increase 40 million kilograms of rapeseed, 10 million kilograms of lint, and increase revenue by nearly 100 million yuan.
