Method for planting under-forest konjak in sunshade net-circle planting mode

Abstract

The invention discloses a method for planting under-forest konjak in a sunshade net-circle planting mode, and belongs to the technical field of crop cultivation. The method comprises the steps that land preparation is conducted on an under-forest idle land, and konjak is planted; the method comprises the following steps: immediately building a steel wire ring after konjak planting, and carrying out ring planting on konjak; the ground clearance of the steel wire rings is 0.4-1.6 m, the number of turns of the steel wire rings is 4-8, and the distance between every two steel wire rings is 10-20 cm; a sunshade net is built in the period from seedling emergence to leaf expansion of the konjak; the shading degree of the sunshade net is 30%-85%, and the distance between the sunshade net and the ground is 2-4 m. According to the method for planting the konjak under the forest in the sunshade net-circle planting mode, the planting range of the konjak under the forest is expanded, the morbidity of the konjak under the forest is reduced, and the yield of the konjak is increased.

Description

technical field [0001] The invention relates to the technical field of crop cultivation, and more specifically relates to a method for planting understory konjac in a sunshade net-circle planting mode. Background technique [0002] In recent years, in order to fully consolidate and utilize the results of returning farmland to forests, further develop the under-forest economy, and respond to the policy of gradually transferring cultivated land to staple food planting, it is inevitable to transfer the cultivation and development of konjac to under-forest. Vigorously developing understory konjac, expanding the suitable planting area of ​​konjac, realizing the complementary advantages of arbor forest and konjac, and creating a suitable growth environment for konjac are the top priorities for the development of konjac in the mountainous areas of southern Shaanxi. Ankang City, located in the hinterland of the Qinling Mountains, is a natural area suitable for konjac planting, mainl...

Problems solved by technology

[0003] But undergrowth konjac has the following problems when developing: first, different types of tree species will affect the plantation of undergrowth konjac, such as black locust, paulownia, chestnut tree and fir etc. are all poor in wind resistance, and there are many fine branches , it is easy to appear wind break, wind down, tilt or partial crown phenomenon at the outlet

However, when planted under walnut trees and chestnut trees, due to diseases, inadequate manual management, and bird pecking, etc., the phenomenon of fruit drop usually occurs at the end of July or early August; at the same time, the fallen walnuts, chestnuts, etc. It will cause animals, insects and birds to move between konjac rows, and then cause further damage to konjac; second, in actual planting, it will be found that due to high mountains and steep roads, uneven density of forests, uneven plots, and lack of artificial labor For other reasons, the planting of konjac under the forest has become "natural planting", and it is difficult to manage finely after planting, that is, relying on the sky for food

Among them, the shady environment under the forest has the greatest impact on konjac. Konjac likes to be planted in a shaded place with short light time, weak light intensity, not direct sunlight, and half shade and half sun. Happening

If the shading is too dense, the light of konjac is insufficient, the stalks are too long, and the undergrou
