Description

Double-layer frame-building planting method for passion flower in karst mountain area

Technical Field

The invention relates to a high-efficiency passion flower cultivation technology, in particular to a double-layer frame-building passion flower planting method in a karst mountain region.

Background

Passiflora edulis (A)Passiflora edulia Sims) Belongs to perennial evergreen climbing grass or semi-woody evergreen vine plants in passion of passion family, is a fragrant and delicious fruit and has the reputation of 'the king of fruit juice'. Commonly known as passion fruit, chronogenesis fruit, guava, brazil fruit, and the like. The fields such as brazil and the like originally produced in south America of passion fruit are distributed and cultivated in Taiwan, Guangdong, Guangxi, Fujian, Yunnan and the like in China at present.

The growth speed of the passionflower is fast, fruits are hung in the same year, blossoming and fruiting can last from 3 months to 12 months in a Guizhou karst mountain area, a frame is not usually built, the passionflower is paved on stony desertification to grow, the fruit yield is generally about 800 jin/mu, but the fruits are easy to scald on the stone surface, the fruit coloring is not good, the commodity is not available, and the sale is influenced.

The invention content is as follows:

aiming at the defects of the prior art, the invention provides a double-layer frame-building planting method for passion flower in a karst mountain area, which is used for ensuring high-efficiency cultivation of passion flower, increasing the yield per unit area, reducing cold injury and freezing injury in winter and ensuring normal overwintering of passion flower branches on the first layer.

The technical scheme adopted by the invention is as follows: a double-layer frame-building planting method for passion fruit in karst mountainous areas comprises the following operation steps:

1) erecting a passiflora climbing frame, wherein the height of the climbing frame is 160-200cm, and the climbing frame is of a double-layer structure;

2) the width of the passion flower planting box surface is 210cm, the length is determined according to the terrain, only one row of passion flowers are planted in each box, the seedling spacing is 200cm multiplied by 200cm, and the distance between the support columns of the climbing frame is 200cm multiplied by 200 plus 400 cm;

3) the first layer of the climbing frame is 130cm away from the soil surface and the second layer is 200cm away from the soil surface;

4) respectively arranging steel wires on one layer and the second layer of the climbing frame, and then paving the steel wires on a steel wire net by using a momordica grosvenori net;

5) two ends of the passion flower box surface are respectively provided with two upright posts, and the two upright posts are provided with steel wires which are tensioned, and the steel wires form an included angle of 45 degrees towards the outside of the box surface;

6) the second layer of passion flower in the karst mountain area is put on the shelf for 7-8 months, and when 80-90% of the shelf surface is covered by the first layer of passion flower branches, 2-3 branches of passion flower branches are put on the shelf surface of the second layer.

Through years of experimental research, the finding that after the first layer is fully paved on the shelf, each plant leads 2-3 branches to the second layer, the finding shows that the yield can be improved by about 1000 jin/mu on the basis of about 2500 jin/mu, the quality of the passionflower is not affected, and in addition, in winter, the upper layer also has the effect of resisting cold injury and freezing injury, and the passionflower branches on the first layer are ensured to normally live through the winter.

By using the double-layer frame building method, the yield per unit area can be increased, the income per unit area can be increased, meanwhile, the normal overwintering of the passion flower branches at the first layer can be guaranteed, the production and construction cost in the second year is reduced, and the overall economic benefit is improved. The method has great significance for planting and popularizing the passion flower in large area in the karst mountain area, reducing the production and construction cost, and establishing the efficient agricultural park in the karst mountain area by applying the efficient cultivation technology of the double-layer shelf.

The specific implementation mode is as follows:

the implementation place is as follows: the Guizhou province Pingtang Kedu Zhengguanming tea field is a high-efficiency characteristic vine plant production and research base in the karst mountain region.
