Quick interplanting and alternate cropping breeding method of konjac

Abstract

A quick interplanting and alternate cropping breeding method of konjac relates to a breeding method including the plant interplanting of konjac rhizome bred plants, konjac seed cultivated plants and corn cultivated plants, and alternate cropping of plant pits. The breeding method has the following advantages that the plant interplanting is capable of filtering out partial sunshine needed by the konjac seed plants by using the corn plants and filtering out the sunshine needed by the konjac rhizome plants by using the konjac seed plants, thereby reducing the occurrence of sunscald, and simultaneously increasing the planting density of the plants and improving the yield of a unit planting area; and the alternate cropping of plant pits is capable of blocking a disease source of plant diseases and insect pests and also capable of continuously producing the konjac seed source so that commercial konjac can be provided every year; and therefore, the supply time of the commercial konjac is shortened.

Description

technical field [0001] The invention belongs to a method for planting crops, in particular to a plant interplanting method for konjac rhizome breeding, planting taro cultivation and corn cultivation and planting nests and stubbles. 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 alka...

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 started to develop industrially. However, due to its late start, there has been no major breakthrough in planting technology, especially in terms of provenance. Since konjac is a perennial plant, the seeds need to be cultivated for 2-3 years before they can grow. As a kind of taro to produce commercial taro, in order to speed up the production speed of konjac, people have thought of many ways. Now the more popular methods are rhizome propagation method, small tuber propagation method and cutting propagation method, etc. These methods are compared with seed propagation. , has greatly accelerated the breeding speed, but it is still insufficient in terms of comprehensive disease prevention and increase per unit yield. Patent No. 200310110792.X has announced "the method for controlling konjac soft rot by planting diversity of konjac and corn", which achieves the control of soft rot through interplanting However, the effect of rational use of sunlight and prevention of sunburn is not ideal, and no consideration has been given to increasing planting density and preventing disease through crop rotation
