Method for improving maturing rate of konjak seeds

Abstract

The invention provides a method for improving maturing rate of konjak seeds. The method comprises the following steps: ridging in a selected land according to the specification of 0.4-0.5 meter wide; sterilizing seed konjaks and ridges; digging a sowing ditch of 15-20 cm deep in a planting belt; placing the selected seed konjaks in the sowing ditch; sowing a row of pea, broad bean, Chinese trumpet creeper or green manure on the ridge face; spraying a herbicide to the ridge face after the sowing is finished; taking a heat and moisture insulating measure to guarantee that the temperature at the florescence is above 21 DEG C and the relative humidity of the air is 75-80 percent when spathes of male konjaks emerge; meanwhile, spraying biogas slurry to the flowers and the flower stalks. By using a planting mode of male konjak concentrated integration and inter-planting of nitrogen fixing crops or green manure, the florescence, the temperature and the humidity are regulated and controlled, insect vectors are attracted for pollination, and the problems of maturing synchronism of the female and male konjaks and difficulty in obtaining seeds from single plants are solved, so that the purposes of improving the maturing rate of the konjak seeds, increasing the propagation coefficient and increasing the seed konjak number are achieved.

Description

technical field [0001] The invention relates to the field of plant seed propagation, in particular to a method for improving the seed setting rate of konjac seeds. Background technique [0002] Konjac is a perennial herb of Araceae. Its unique physical and chemical properties make it widely used and developed. It has expanded from a single food application to the fields of medicine, chemical industry, textile, printing and dyeing, and petroleum. It has the reputation of "industrial monosodium glutamate". Konjac has a wide range of uses, great development potential, and good market prospects. It is called a sunrise industry in the new century. [0003] At present, the main method of konjac seed propagation is: using small bulbs, rhizomes and other vegetative propagation methods for cultivation. This method of seed propagation has a low coefficient and is difficult to meet the demand for a large amount of seeds for production. With the expansion of artificial cultivation and ...

Problems solved by technology

However, due to the different ripening characteristics of male and female konjac, that is, the female flowers are ripened 2 to 3 days earlier than the male flowers, and the fertilization time of the pistil is short, and a single plant cannot be pollinated and fertilized, so it is difficult to obtain "seeds" by natural means.
