A method for breeding gladiolus in a solar greenhouse

Abstract

The invention discloses a gladiolus crossbreeding method using a sunlight greenhouse. Seeds are sown within the mid-to-end of August and the first ten-day period of September when the outdoor highest temperature in not higher than 29 DEG C; cold protection, heat preservation and ventilation are carried out after seedball treatment, soil treatment, soil preparation, sowing and hauling are carried out; daily management refers to moisture management, humiture management and topdressing; artificial pollination is carried out after flowering at the last ten-day period of November in the same year; and seeds are mature 5-6 weeks later. The gladiolus crossbreeding method can greatly delay the flowering phase, effectively solves the inconsistent flowering phase problems of different varieties, and simultaneously provides enough artificial pollination time for crossbreeding work, reduces workload because bagging is not needed before and after flowering, the operation of stamen removal is only carried out before pollen sacs break, and bagging is also not needed before and after pollination, and greatly increases maturing rate, wherein the maturing rate is over 80% and each capsule contains over 60 grains. By adopting the sunlight greenhouse for crossbreeding, the sowing time is delayed, and seasons with high temperature, high humidity and abundant rainwater are avoided, fruit setting is favored and insect pest is prevented.

Description

technical field [0001] The invention relates to a technique for planting gladiolus, in particular to a method for breeding gladiolus in a solar greenhouse. Background technique [0002] Conventional crossbreeding method of gladiolus: sow seeds in March-April every year, plant in the open field, bloom in June and July of the year, and then carry out artificial crossbreeding. Disadvantages of conventional methods: 1. Diseases, insects, and weeds are serious. Sowing in March-April, flowering in June-July. At this time, diseases, insect damage, and weed damage are heavy, often causing fruit pods to be eaten by pests, large areas of plants die, weeds are overgrown, and management costs are increased. 2. The flowering period is short. Due to the high external temperature, the lifespan of individual flowers and group flowers is short. On the one hand, the flowering period of different varieties does not meet. On the other hand, the time for artificial pollination is short, and th...

Problems solved by technology

Disadvantages of conventional methods: 1. Diseases, insects, and weeds are serious

At this time, diseases, insect damage, and weed damage are heavy, often causing fruit pods to be eaten by pests, large areas of plants die, weeds are overgrown, and management costs are increased.

2. The flowering period is short. Due to the high external temperature, the life of a single flower and a group of flowers is short. On the one hand, the flowering period of different varieties does not meet. On the other hand, the artificial pollination time is short, and the total amount of hybrid seeds available is greatly reduced.

3. Heavy workload

On the one hand, it increases the temperature and humidity in the bag, which is not conducive to the hardening of gladiolus; on the other hand, it greatly increases the workload

4. Poor seed setting rate
