90% of the soil in the province is deficient in boron, and the area of ​​severe boron deficiency accounts for more than 70%. The application of boron to crops has become an important technical measure in agricultural production. The new boron fertilizers such as Fuguan quick-acting boron fertilizer and boron-holding boron have the advantages of high boron content, good water solubility, fast absorption speed and easy absorption. They are applied on boron sensitive crops such as rapeseed, cotton and peanut, and the effect of increasing yield and income is very obvious.
1. According to the characteristics of rapeseed, cotton, peanut and other crops and soil boron supply, it should be applied according to local conditions. Boron fertilizer should be applied to the soil with effective boron content below 0.8 mg/kg.
2, based on boron fertilizer. Before planting or transplanting crops, use 1 package (400 g) of boron-rich per acre or 1 pack of boron (200 g) with other fertilizers, and mix them with other fertilizers, apply them to the soil layer. . At the same time of mixing boron fertilizer and chemical fertilizer, adding fine organic fertilizer mixed application (combined organic fertilizer and chemical fertilizer 1:1) is beneficial to uniform application, and organic fertilizer can play a protective film effect and improve fertilizer efficiency. The base application of boron fertilizer should be applied to the soil to reduce the loss of fertilizer efficiency.
3. Spray boron fertilizer. In the rapeseed twitching stage, cotton seedling stage, early flowering stage, peanut seedling stage, flowering and down-needle period, one package (50 grams) of rich-capped quick-acting boron fertilizer per acre is dissolved in 25 kg of water for foliar application to crops. The leaves are moist and the water is not dripping. The spraying time should be carried out on a sunny afternoon. If it is rained within 4 hours after spraying, it should be sprayed once.
4, matters needing attention. Avoid direct contact with crop seeds and roots so as not to affect seed germination and burn crop roots. The test shows that the application of new boron fertilizer such as Fuguan is 10-20% higher than that of non-boron fertilizer, and the income from mu is 30~50 yuan, and the ratio of production to production is 1:5, which improves the fertilizer utilization rate by 3-5 percentage points.
In 2006, it plans to build 20 counties and cities in Wujia, Lishui, Huangmei, Ezhou, Daye, Anlu, Tianmen, Xiantao, Shayang, Xiangyang, Nanxun and Hong'an in the key rape producing areas of the province. Demonstrate 4 million mu. According to the increase of 15 kg of rapeseed and 10 kg of lint, the province can increase the production of 40 million kg of rapeseed and 10 million kg of lint, with an increase of nearly 100 million yuan.
