Method for breeding hybrid seed of gauze room cucumber

Abstract

The invention discloses a method for breeding hybrid seeds of gauze room cucumber and relates to the technical field of crop cultivation. The method comprises the following steps: respectively carrying out planting fixation on a father plant and a mother plant for breeding seeds, and isolating by using gauze. Due to adoption of the gauze, cucumber seedlings can be protected, and damage caused by wind and frosting can be alleviated; meanwhile, insect pollination and hybridization of other species which can affect seed purity can be also prevented, and a part of insect infected plant diseases and insect pests can be prevented; in addition, in cross pollination, female flowers to be bloomed do not need to be capped, but only female flowers of the mother plant and male flowers of the father plant after pollination are clamped by using grafting clamps, then pollination operation can be completed, the working intensity can be greatly alleviated, the labor can be saved, the production cost can be reduced, and in addition, the seed purity can be well ensured.

Description

technical field [0001] The invention relates to the technical field of crop cultivation, in particular to a method for hybrid seed production of cucumbers in nethouses. Background technique [0002] According to statistics, the planting area of ​​cucumbers in 2017 was about 20 million mu. Such a large planting area requires a lot of cucumber seeds. Producing such a large amount of cucumber seeds is to increase the planting area on the one hand, which increases the waste of land resources in the planting area and increases production costs. On the other hand, increase the yield of hybrid seed production from the production technology. [0003] The traditional cucumber hybrid seed production technology adopts open field production, which is greatly affected by natural climate conditions, and has the following disadvantages: 1. Low pollination and seed setting rate at high temperature, low seed production yield; 2. Insect pests in open field seed production Serious, and insec...

Problems solved by technology

[0003] The traditional cucumber hybrid seed production technology adopts open field production, which is greatly affected by natural climate conditions, and has the following disadvantages: 1. Low pollination and seed setting rate at high temperature, low seed production yield; 2. Insect pests in open field seed production Serious, and insect pests can infect seeds with bacteria; 3. The production cost is relatively high, and only 20 labors per mu are wasted for the female flower before pollination; 4. Cucumber is an insect-borne flower, and it is difficult to improve the purity of seeds affected by insects in the open field
