Method for producing amorphophallus konjac hybrid seedling seeds with pollinating insects

Abstract

The invention relates to a method for producing amorphophallus konjac hybrid seedling seeds with pollinating insects. The method has a basis of the following 4 key technologies: (1) systematic investigation is carried out upon flower-visiting insects; (2) pollinating insects are further screened from the flower-visiting insects; (3) insects which can be applied in field pollinating seed production are selected from the pollinating insects; and pollinating capacity and effects of the insects are verified; and (4) one or more types of pollinating insects are used in collaborative pollination, or flower-visiting frequency is improved with a hyperchromic effect or by artificially adding a carrion-type low sulfur ether material, such that group seed setting rate and single-plant setting rate are improved. According to the invention, carrion-type insects such as flesh fly, earwig, beetle and rove beetle are used for pollinating, such that production efficiency can be improved, and labor cost can be reduced. The hybrid large-scale seed production cost is substantially lower than artificial pollination cost, such that insect pollination has certain industrial prospect. The insect pollination method also has great practical significance for biodiversity protection and resource conservation.

Description

technical field

[0001] The invention belongs to the technical field of agriculture and relates to a seed production method, in particular to a method for producing konjac hybrid seeds by using pollinators. Background technique

[0002] Flower konjac (AmorphphalluskonjacK.Coch) belongs to the perennial semi-negative herbaceous plant of Araceae Konjac, which accounts for more than 90% of the cultivated area of ​​about 2 million mu in the world. 10%, because it is rich in glucomannan, it is widely used in special foods, functional foods and health products. It is a highly efficient and characteristic economic crop in the mountainous areas of southwest my country. However, the accumulation of diseases and species degradation caused by long-term vegetative propagation have seriously threatened the sustainable development of konjac industry, which is manifested in the stagnation or even regression of the cultivated area, the gradual decline of cultivation benefits, and the increasi...
