Banana directional low-position secondary bud reserving and fruiting plant selecting method

Abstract

The invention provides a banana directional low-position secondary bud reserving and fruiting plant selecting method. The banana directional low-position secondary bud reserving and fruiting plant selecting method comprises the following steps that (1), a banana bud reserving period is selected according to planned harvesting time; (2), a suction bud which is 10-20cm away from the banana stock plant and has an insertion depth of below 8cm is reserved as a first-grade bud, all the rest suction buds are removed, and a growing point is destroyed; (3), after the first-grade bud grows to the height of more than or equal to 1m, soil leveling treatment is carried out at positions which are symmetrical on two sides of bud heads and are in rows with front and back banana plants; (4), a bud promoting agent is sprayed; and (5), after new suction buds on the periphery of the first-grade bud grow out, a second-grade suction bud which is 10-20cm away from the first-grade bud at the leveling position and has the penetration depth of below 8cm is selected as a fruiting plant. By means of the method, banana directional low-position bud reserving is achieved, the outcrop proportion is greatly reduced, the problems that in an existing banana bud reserving technology, buds are prone to outcropping after being sucked and the growth position and the growth period are irregular are solved, and the high-quality banana bud reserving cultivation method is simple, convenient, fast and stable.

Description

technical field [0001] The invention relates to the technical field of banana planting, in particular to a method for selecting fruiting plants by directional low-position secondary bud retention for bananas. Background technique [0002] Banana (Musa paradisiacea var. sapientum) is an important economic crop in the tropics and subtropics in my country, and it is also the fourth largest food crop in the world. It has a cultivation history of more than 3,000 years in my country. Its fruit is sweet and delicious, rich in nutrients, and loved by people. [0003] There are mainly three kinds of existing banana cultivation methods, which are respectively planting tissue culture seedlings, transplanting and sucking buds and cultivating with buds remaining. The management cost of planting tissue culture seedlings is relatively high, and it is usually suitable for the development of new banana orchards. Although the initial investment in transplanting and sucking buds is less than ...

Problems solved by technology

[0004] But there are also obvious shortcomings in the traditional banana garden with bud retention, because the suction buds are directly retained as the fruiting plants, and the suction buds cannot be seen when the suction buds are retained. To the depth of bud-sucking, bananas with buds are often easy to outcrop, and bananas are prone to lodging after outcropping

In addition, because banana suckers grow around the corm, different suckers grow in different sizes and positions are not fixed, so if you choose suckers with neat positions when selecting buds, their growth will be irregular; if you choose suckers with neat growth If there are no buds, the growth position will be irregular, and the longer the cultivation period of the buds, the more serious the problem of outcropping and irregularity of bananas, resulting in the growers are often forced to renew the banana orchard due to defects

[0005]Therefore, in view of the problems that bananas are easy to outcrop and the growth position and growth period are not uniform in the existing budding cultivation method, the present invention proposes a banana orientation low-level secondary The method of retaining buds to select fruiting plants provides an important technical basis for the high-quality, low-cost cultivation method of bananas retaining buds
