Method of improving and raising quality of rice-transplanting groups for seed production machine by utilizing wheat packing

Abstract

The invention discloses a method of improving and raising quality of rice-transplanting groups for a seed production machine by utilizing wheat packing. The method is characterized in that during the seed-production and sprout cultivation processes of hybrid rice, bonding strength of seedling roots by machine-transplanted seedling is improved by controlling sowing amount of transplanted rice from male and female parents, proportionally adding proper amount of wheat seeds and utilizing bonding strength of wheat seedling roots in order to help interwine rice in plastic plates; therefore, the sowing quantity of rice is reduced and cost is saved; quality of transplanting groups is raised; manual curling, transport, machining and transplanting are conveniently performed in the late period of machine-transplanted seedling in order to satisfy the requirement for machine-transplanted seedling by a machine so that no wheat is forgotten to be transplanted; after transplanting, during early tillering in groups for seed production regeneration, population quality of seedlings on land for growing field crops is easily produced; after transplanting, wheat seedlings cannot take root and grow in paddy fields due to growth characteristics of wheat; no adverse effect is exerted on growth of rice population so that quality of seedling groups is improved; and finally, seed production is improved and the effect of saving cost and enhancing efficiency is significant.

Description

technical field [0001] The invention relates to a method for improving and increasing the quality of machine-transplanted seedlings by taking advantage of the advantages of strong coiling force of wheat roots in the field of hybrid rice seed production and seedling raising. By sowing rice and wheat at the same time, using the advantages of well-developed roots and hairs of wheat seeds, strong coiling force, and easy to curl and not break in the later stage to assist machine-transplanted seedlings to intertangle with each other in the soft disk or hard disk of the seedling, so that the overall seedlings are firm and not easy to disperse. It is easy to curl manually, easy to transport and easy to use on the machine. After machine transplanting, it can significantly promote the green growth of seedlings, promote tillering and ear increase, and effectively increase the yield of seed production. The method can reduce the amount of rice seeds used, especially the amount of seeds use...

Problems solved by technology

[0008] The purpose of the present invention is to overcome the poor quality of the existing hybrid rice seedling raising stage, especially the poor quality of the seedling raising group of the sterile line, the root system is not firm, the root packing is uneven in thickness, the artificial curl is easy to break, and the seedlings are soiled. Easy to disperse, easy to break the seedling board on the machine, etc., provide a machine-transplanted floppy disk or hard disk seedling raising method that increases the transplanting population of the hybrid rice seed production machine with high quality and is helpful for mechanical planting
