High-yield and high-quality cultivation method for fusarium wilt-resistant banana varieties

Abstract

The invention discloses a high-yield and high-quality cultivation method for an anti-wilt banana variety. The method comprises the steps that the low-order planting anti-wilt banana variety is adopted for tissue culture seedlings; when the low order means soil preparation or planting, the ground of a planting hole is lower than a garden bed face, a step is formed, the paddy field banana garden level difference is 8-15 cm, and the mountain land banana garden is 14-22 cm; when banana plant corms begin to appear, earthing is performed to protect corms, and root growth is promoted. During early spring planting, the low planting density is adopted, plants can fruit earlier, and plants are prevented from fruiting or being frozen in winter; in summer and autumn, high planting density is adopted for planting, the yield per unit area can be increased, and meanwhile fruit quality is not affected; paper bags and nutritional agents are used for plant ears, so that the problem that fruits become green physiologically can be solved. According to the high-yield and high-quality cultivation method customized for the anti-wilt banana variety, the culture technology can achieve high yield, good quality and high benefits and achieves the great production significance.

Description

technical field [0001] The invention belongs to the field of banana cultivation, and in particular relates to a high-yield and high-quality cultivation method for fusarium wilt-resistant banana varieties. Background technique [0002] Fusarium wilt of banana has become the most threatening disease in the world. In 1996, No. 4 species of Fusarium wilt was found in Wanqingsha Town, Guangzhou City, Guangdong Province. Now this devastating disease occurs in varying degrees in the banana production areas of the whole province and even the whole country. Many bananas The garden has been abandoned for bananas. In the past ten years, the Fusarium wilt-resistant varieties such as 'Nongke No. 1 Banana' and 'Kangku 1 No. Banana', 'Nantian Huang Banana', 'Yueke No. 1 Banana', etc., have certain applications in production. However, compared with the main planted varieties such as Brazilian banana, they all have many planting difficulties: for example, the growth cycle is longer (more t...

Problems solved by technology

However, compared with the main planted varieties such as Brazilian banana, they all have many planting difficulties: for example, the growth cycle is longer (more than 6-8 leaves are drawn more than the main planted variety 'Brazilian'), "outcropping", The cold resistance is slightly poor, and the "Qingdan" (also known as "jumping" or "two-stage coloring") phenomenon of uneven ripening on the fruit fingers affects the appearance and thus affects the economic benefits of production; in addition, the pathogenic bacteria and root nematodes in the soil Presence, increasing incidence of resistant cultivars

However, there is currently no professional research on cultivation methods for fusarium wilt-resistant banana varieties. Banana farmers still use past experience and planting methods to deal with fusarium wilt-resistant banana varieties
