Breeding equipment for crop seeds and breeding method

Abstract

The invention provides breeding equipment for crop seeds and a breeding method. The breeding equipment for the crop seeds comprises a water tank, a seedling raising box and a box cover, wherein an irrigation mechanism is arranged in the water tank and comprises a water inlet pipe, a submersible pump and a water conveying pipe, the seedling raising box is fixed to the top end of the water tank, ventilation holes are formed in the two ends of the seedling raising box, ventilation mechanisms are arranged in the two ventilation holes, an electric heating net is fixedly embedded in one ventilation hole, each ventilation mechanism comprises a fixing hole, a ventilation fan and a dust filtering net, a plurality of separation mechanisms are arranged in the seedling raising box, and each separation mechanism comprises a limiting groove and a separation plate. The breeding equipment can ensure that the humidity of seedling culture base soil and the temperature of air are in the optimal humidity range of breeding; and according to the equipment, multiple groups of breeding experiments can be simultaneously carried out in the same breeding box, so that variable control is more accurate, meanwhile, the breeding time can be shortened, and the problems of inaccurate variable control and relatively long breeding time in the prior art are solved.

Description

Technical field [0001] The present application relates to the field of crop breeding, in particular, involving breeding equipment and breeding methods of crop seeds. Background technique [0002] Breeding is the technique of cultivating new varieties of excellent plants by creating genetic variations, improving genetic characteristics. Based on genetics, it is integrated with various disciplines such as ecological, physiological, biochemical, pathological and biological statistics. It is very important to develop animal husbandry and planting industry. Conventional breeding has hybrid breeding, long-term hybrids; very bracing has mutagenic breeding, molecular breeding and ex vivo culture techniques, wherein the uncontrollable factors of mutagenesis breeding are more, and the control variables are generally used. Method is operated. [0003] Patent 1: According to the "An UV mutagenesis breeding box" disclosed in China's utility model (Application Note: CN201320541200.9), it inclu...

AI Technical Summary

Problems solved by technology

[0007] (1) The technical problem to be solved in the present invention is: temperature, humidity, ventilation rate and physical mutagenesis source etc. are not accurately controlled, which will affect the effect of breeding, and in specific use, a plurality of breeding boxes are needed simultaneously operation, so that the control of variables will be more inaccurate; or use the same breeding box to breed in batches, which will undoubtedly prolong the breeding time
