Under-forest planting and ecological fertilizing method for konjak

Abstract

The invention relates to an under-forest planting and ecological fertilizing method for konjak. According to the method, the konjak is planted by modes of the selection of forest lands, the planting of green manure and the reduction of the using amount of industrial fertilizers, so that the utilization efficiency of lands can be improved, and discarded areas in forests are changed into crop planting fields which can be utilized effectively; the konjak is shade-loving and can be prevented from being irradiated by sunlight under the forests while obtaining part of sunlight, so that the quality of the konjak can be improved, and the yield of a single plant can be increased; broad bean green manure is planted, so that a large number of ecological fertilizers can be provided, the using amount of the industrial fertilizers can be reduced, and the quality is improved while the yield is ensured; and the broad bean green manure contains a large number of symbiotic rhizobia, so a large number of ecological nitrogen fertilizers can be provided for the planting of the konjak, pathogenic bacteria are prevented from being generated on the konjak, and the diseases of the konjak are reduced.

Description

technical field [0001] The invention belongs to the technical field of crop cultivation, in particular to a method for understory planting and ecological fertilization of konjac. Background technique [0002] Konjac, also known as Konjac, belongs to the perennial tuber herbaceous plant of Araceae; it is mainly produced in the tropical and subtropical regions of the Eastern Hemisphere, and China is one of its origins. Sichuan, Hubei, Hunan, Yunnan, Guizhou, Shaanxi, Guangdong, Guangxi, Anhui, Fujian, Taiwan There are many kinds of konjac, there are more than 260 varieties in the world, and 21 kinds in China, 8 of which are endemic to China. [0003] The history of the application of konjac in our country was first seen in Tao Hongjing's "Famous Doctors" in the Wei and Jin Dynasties. Konjac was first recorded as a medicine, and later medical works of all dynasties were compiled. method. [0004] Konjac is a beneficial alkaline food. For people who eat too much animal-based a...

Problems solved by technology

In 2006, domestic and foreign demand for fresh konjac was 900,000 tons, while the output was only 520,000 tons, far from meeting the demand

[0007] Since the 1980s, Chinese konjac has begun to develop industrially. However, due to the late start, there has been no major breakthrough in planting technology. At the same time, the planting area has also been greatly limited, so that the total output cannot be effectively increased.

A more effective way to expand the planting area is to interplant konjac under the forest, as Patent No. 201010173249.4 announces "a kind of cultivation method for interplanting flower konjac under the forest", adopting selection of forest land, sparse forest preparation, sowing, reasonable dense planting, field Management, step-by-step digging and other steps, using fallen leaves to provide winter heat preservation and fertility for konjac. Although this method has a certain effect, it does not take measures for fertilization and soil protection. Over time, it will have adverse effects on the soil and forests.
