Greenhouse seed production method of thick-skinned muskmelon

Abstract

The invention relates to a method for producing thick-skinned muskmelon seeds in a facility greenhouse. The solar greenhouse is used to produce thick-skinned muskmelon seeds in early spring. The ratio of parental parents is 1:5. The male parent is sown 7 days earlier than the female parent, and the seedlings reach 3 leaves and 1 heart. When planting, water thoroughly, hoe and cover plastic film, perform single-stem pruning on the female parent, and hang vine cultivation, pick the heart when 20-22 leaves, leave melons at 16-19 nodes, leave 3-4 vines on the male parent for hanging vines, and remove side buds. Select 3 to 4 vines for pollination, emasculate after 4:00 p.m. one day before the female flowers bloom, and cover them with a sleeve. Pick the male flowers at 5-7 o'clock the next day, cross-pollinate the emasculated female flowers at 7-10 o'clock, and pollinate After the completion, cover it with a bag, keep 3 hybrid melons until the size of an egg, and choose 2 melons. The method utilizes greenhouses for thick-skinned melon breeding, avoids the flowering period of various wild Cucurbitaceae species and vegetables, reduces the probability of hybridization, greatly improves the purity of seeds, reduces the impact of bad weather on the growth of melons, and improves the quality of seed production. more secure.

Description

technical field [0001] The invention relates to the technical field of crop seed production, in particular to a greenhouse seed production method for thick-skinned melon facilities. Background technique [0002] Melon, also known as cantaloupe, fruit melon, sweet melon, etc., is an annual vine herb of the Cucurbitaceae Melon genus. It can be roughly divided into two categories, thin-skinned melon and thick-skinned melon. Thin-skinned melon is native to my country and is cultivated in various regions of my country. It has the advantages of strong adaptability and easy cultivation, but it is not resistant to storage and transportation. The single melon is small and its quality is not very outstanding. Thick-skinned melons are not native to China. They are big, thick, of good quality, and resistant to storage and transportation. They are the main melons in Europe and the United States. Through historical introductions and exchanges, thick-skinned muskmelons can be grown in open...

Problems solved by technology

[0003] Although with the continuous efforts of breeding experts, thick-skinned melon varieties that can be cultivated in protected areas in mainland China have been bred, but the yield of melons is still low in the process of cross-breeding, and the quality and purity of seeds are difficult to be effective. Control, high production costs and other issues, these problems have restricted the development of the melon seed industry to a certain extent

On the one hand, due to the continuous improvement of the multi-cropping index of melons as a facility, the crop rotation period is shortened, and the soil continuous cropping obstacles are intensified. As a seed production land, it has a greater impact on the yield of melon seeds; on the other hand, due to the lack of high-yield seed production technology, blindly increase the number of melons. , the plant nutrition cannot be effectively supplied, leading to premature aging of the plant, and it is difficult for melons to mature

There are also some such as unscientific pollination time and pollination cycle, and the pollination environment is not single, resulting in a decrease in hybrid fruit set rate and more false hybrids

Uneven pollination, excessive damage to female flowers, prone to deformed fruit and non-set fruit
