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...

AI Technical Summary

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 underground bulbs cannot grow and expand effectively; if the shading is too sparse, the shading effect is not good, and the high temperature and direct sunlight in summer are easy to cause leaf damage, yellowing, premature aging of the plants, and affect the final Third, the limitation of the under-forest environmental conditions, (1) the under-forest gully is uneven, and the low-lying places are prone to form water during the rainy season, which affects the growth of konjac; The corm grows slowly and expands slowly, which affects production efficiency; (3) It is generally difficult to walk between the sidewalks and konjac rows under the forest, and the narrow road is steep, and it is easy to be slippery and difficult to carry out agricultural operations in the rainy season or autumn and winter; (4) Under the forest There are many small shrubs and weeds, which makes weeding an important task in the process of planting Amorphophallus konjac under the forest, resulting in the consumption of manpower and financial resources.

(5) If there is continuous rainy weather in mountainous areas, it is very easy to cause landslides or mudslides of varying degrees, which will cause damage to konjac planting under the forest every year, affecting production and development

Fourth, forest animals such as birds, pheasants, hares, wild boars, etc., often cause large-scale lodging and damage to konjac, causing great economic losses to taro farmers
