Problems solved by technology

At present, in addition to using chemical agents for prevention and control, there are also methods for using biological agents for prevention and control. For example, Chinese patent CN102742448 A discloses a technology for applying Bacillus cereus to bananas. However, Bacillus itself is a pathogenic bacterium, and improper use of Bacillus will cause secondary infection of bananas. Therefore, in the process of planting bananas, it is necessary to find a method that can effectively prevent and control root-knot nematodes. A method that will not cause secondary pollution, and currently there is no public disclosure of the purpose of preventing and controlling root-knot nematodes through multiple cropping methods

Embodiment 1

[0027] The soil in the nursery is plowed and crushed, the topsoil is mixed with lime powder, exposed to the sun, and the tissue-cultured banana seedlings are cultivated in the greenhouse according to the local living conditions, and the seedlings are transplanted after the cultivation is completed; : The double-row deep ditch and high-row planting method is used for planting. The width of the furrow is 5m, and a deep ditch with a width of 40cm and a depth of 60cm is opened around the furrow. , fixed-point digging, the length of the pit is 50cm, the width is 50cm, and the depth is 20cm. In the pit, backfilling thickness is the banana substrate fertilizer of 2cm (the composition of substrate fertilizer is: 40% organic fertilizer, 30% green manure, 20% lime , 10% topsoil), irrigate with water, and cover with plastic film; uncover the plastic film, select the healthy seedlings that have been cultivated and dig deep pits for planting, check the row spacing of banana seedlings, backf...

[0029] The soil in the nursery is plowed and crushed, the topsoil is mixed with lime powder, exposed to the sun, and the tissue-cultured banana seedlings are cultivated in the greenhouse according to the local living conditions, and the seedlings are transplanted after the cultivation is completed; : It is planted with double-row deep ditch and high-brow planting method. The width of the furrow is 6m, and the furrow is surrounded by a 50cm wide and 70cm deep ditch. , fixed-point digging, the length of the pit is 70cm, the width is 70cm, and the depth is 30cm. In the pit, backfilling thickness is 5cm banana matrix fertilizer (the composition of the matrix fertilizer is: 60% organic fertilizer, 20% green manure, 15% lime , 5% topsoil), pour water thoroughly, and cover the plastic film; uncover the plastic film, select the healthy seedlings that have been cultivated and dig the deep pits for planting, check the row spacing of the banana seedlings, backfill the middle pile of soil ...

Embodiment 3

[0031] The soil in the nursery is plowed and crushed, the topsoil is mixed with lime powder, exposed to the sun, and the tissue-cultured banana seedlings are cultivated in the greenhouse according to the local living conditions, and the seedlings are transplanted after the cultivation is completed; : The double-row deep ditch and high-row planting method is used for planting, the width of the furrow is 5.5m, the width of the furrow is 45cm, and the depth is 65cm. The middle pile of soil is 45cm high as backfill soil. It is 2.5m, fixed-point digging, and the length of the pit is 60cm, and the width is 60cm, and the depth is 25cm, and backfilling thickness in the pit is the banana substrate fertilizer of 3cm (the composition of substrate fertilizer is: the organic fertilizer of 55%, the green manure of 27%, the green manure of 10 % lime, 8% surface soil), pour water thoroughly, and cover the plastic film; uncover the plastic film, select the healthy seedlings that have been culti...

Abstract

The invention belongs to the technical field of fruit tree planting and cultivation and discloses re-cropping cultivation technology of bananas with resistance to root-knot nematodes. The technology utilizes potatoes and banana seedlings for re-cropping and utilizes marigolds and robust banana seedlings to re-crop so that the purpose of eliminating root-knot nematodes is fulfilled. The planting steps comprises seedlings growing, soil preparation, fixed planting, re-cropping of potatoes and seedling period management, sound seedling period management, fruit tree management and re-cropping of marigolds. By enhancing management during plantation, continuously researching and creating a sound ecological environment for bananas, potatoes and marigolds, root-knot nematodes can be effectively prevented and survival rate of banana fruit trees is increased and soil utilization rate is improved.

Description

【Technical field】 [0001] The invention relates to the technical field of fruit tree planting and cultivation, in particular to a multiplanting cultivation technology of bananas resistant to nematode damage. 【Background technique】 [0002] Banana, a tropical fruit, is widely loved by everyone because of its fragrance and nutrition. Banana can be harvested all year round, and it is also highly valued in temperate regions. It is widely planted in southern my country. Due to the rapid growth of banana tissue culture seedlings With the development and vigorous promotion, the banana planting area is getting larger and larger, and the nematodes encountered in the production and the harm generally occur. The edges are dark brown, and when severe, the epidermis rots, which makes the plant grow slowly and stunt. Moreover, root-knot nematode spreads quickly, has a long dormancy period for eggs, and has good tolerance. If it cannot be controlled in time, it will cause yellowing and wilti...
