Through demonstration and promotion, good economic and social benefits have been achieved. The summary is as follows, for the majority of banana operators.
1 Implementing the Rotary Garden System
After planting 2-3 years in the banana planting area, crop rotation should be carried out to replace the land. Planting rice, peanuts, sugarcane, etc. should be suitable for rotation, especially with rice rotation. For the banana area with limited land conditions, the gully rotation is planted every three years. The method is to cultivate a large amount of foreign soil or pile up a large amount of decomposed organic fertilizer in the middle of the two hoe, and then plant the sorghum. A reasonable rotation is adopted to effectively regulate the soil physical and chemical properties, reduce soil compaction, reduce the occurrence of pests and diseases, and increase banana yield and quality.
2 Do a good job of soil disinfection
The old planting garden has long been cultivated for many years. The soil deposits a lot of toxins and cannot be decomposed or settled effectively. It is extremely unfavorable to banana production. It must be thoroughly cleaned and sterilized once or twice a year. After the harvest of bananas, the garden is fully cleared, and banana leaf is chopped, the nutrients are returned, and lime or other soil disinfectants are applied to neutralize some of the acidity in the soil. -50 cm, which can not only cover all the banana leaves in the garden under the soil, allow it to rot, increase the organic matter of the soil, but also release the trace elements in the deep soil, and continuously improve the soil aggregate structure. Reduce soil compaction.
3 Increase organic fertilizer, improve soil structure, restore soil fertility
Increase organic fertilizer and biotechnology to improve soil, improve the soil microbial structure of the old plantation, increase soil organic nutrients, restore soil fertility, and increase the yield and quality of the old planting area. The specific approach is as follows: First, before the farming, turn the banana plantation land, choose a sunny day after sunburn for a long time; second, before the planting of the banana plantlets, pile up the decomposed organic fertilizer as a base fertilizer and apply the organic fertilizer before the buds; Organic soil rich in indigenous soil is used for cultivation in banana plantations. The fourth is the use of a solid fertilizer with enzyme bacteria in the plantation or 1-2 applications of enzyme liquid fertilizer per month.
4 Plant resistant varieties
The long-term use of bananas and chemical pesticides for successive years has caused more and more serious pests and diseases in the old plantation. Therefore, it is particularly important to plant disease-resistant banana varieties in the old banana plantation area, especially for planting important diseases and devastating diseases such as withering bananas. Disease and leaf spot varieties. At present, banana wilt and leaf spot have different degrees of occurrence in various banana regions in China. The average banana garden has a 10%-20% incidence rate, and individual severe cases range from 70%-90%. It seriously affects the old banana area. Banana production. The selection of disease-resistant varieties can better prevent the occurrence of diseases and effectively increase the yield and quality.
5 Strengthen research on prevention and control of major pests and diseases
One of the main reasons for the low yield and poor quality in the old banana growing area is the serious damage to the pests. The main diseases such as leaf spot, root nematode disease, and banana wilt disease have not yet achieved a good cure. The occurrence of these diseases caused a reduction in production, and the loss of crops caused a devastating blow to the entire banana industry. Therefore, strengthening research on the prevention and control of major pests and diseases of bananas and formulating practical and comprehensive prevention and control measures are effective ways to reduce the occurrence of major pests and diseases in bananas.
6 Standardized production
Established a four-level banana steering group at the city, county (district), township (township) and village level to guide the standardized production of bananas and strengthen the banana production process and production
