Method for producing seeds by adopting cucumis melo facility in greenhouse

Abstract

The invention relates to a method for producing seeds by adopting cucumis melo facility in a greenhouse. According to the method, seeds of cucumis melo are produced in the solar greenhouse in early spring, the ratio of male and female parents is 1:5, male parents are 7 days earlier sown than female parents, planting and thorough watering are performed after a seedling has three leaves and one bud, intertillage is performed, a mulching film is covered, single stem training is performed on the female parents, vine-hanging cultivation is performed, pinching is performed when the seedling has 20-22 leaves, 16-19 nodes are used for fruit reserving, 3-4 vines are reserved for the male parents and hung, lateral buds are removed, 3-4 lateral vines are selected for pollination, emasculation is performed on female flowers at four o'clock in the afternoon one day earlier before the female flowers blossom, male flowers are well sleeved with sleeves, the well-sleeved male flowers are picked up at 5-7 o'clock next day, the emasculated female flowers are subjected to cross pollination at 7-10 o'clock and well sleeved with bags after pollination is completed, three hybrid melons are reserved, and two melons are selected when the three hybrid melons grow to the size of an egg. According to the method, the greenhouse is used for seed breeding of the cucumis melo, the flowering periods of wild species of various cucurbitaceae and vegetables are avoided, cross breeding probability is reduced, the seed purity is greatly improved, influence of adverse weather on melon growth is reduced, and the produced seed quality is better guaranteed.

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 ope...

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
