Problems solved by technology

[0004] In view of the above problems, the technical problem to be solved in the present invention is to provide a kind of method for retaining seeds to improve the germination rate of wax gourd seeds. This method is aimed at the low germination rate of new wax gourd seeds at present. Difficult to operate and other problems, by adjusting the post-ripening and seed-picking process of seed melons, a simple and feasible method for retaining seeds of freshly harvested wax gourd seeds is found to effectively increase the germination rate of new wax gourd species, accelerate the process of wax gourd breeding, and promote the growth of wax gourd. Production, using the seed dormancy obtained by the method of the present invention is shallow, without pretreatment, can obtain a higher germination rate

Embodiment 1

[0021] A kind of seed retention method that present embodiment improves wax gourd seed germination rate, comprises the following steps:

[0022] (1) Management and harvesting of melon seeds: during the growth period of melon seeds, daily management is carried out according to the normal growth requirements of the plants to prevent sunburn, and the vines of the melon seeds grow for 50 days during the whole growth period of the melon seeds, and then the vines are harvested; the daily management Including: cut off all the side vines on the main vine from the vine drawing stage to the flowering stage, and only keep a thick main vine, and manage it with a single vine and a single melon; when the flowers are in full bloom, take the male flowers that have just opened to pollinate the female flowers. The female flower is pollinated by 2 male flowers; the method for preventing sunburn is as follows: in the fruit expansion stage, use newspapers to fold into an inverted funnel shape and c...

[0027] A kind of seed retention method that present embodiment improves wax gourd seed germination rate, comprises the following steps:

[0028] (1) Management and harvesting of melon seeds: daily management is carried out according to the normal growth requirements of plants during the growth period of melon seeds, to prevent sunburn, and the vines of melon seeds grow for 55 days in the whole growth period of melon fruits, and then the vines are harvested; the daily management Including: cut off all the side vines on the main vine from the vine drawing stage to the flowering stage, and only keep a thick main vine, and manage it with a single vine and a single melon; when the flowers are in full bloom, take the male flowers that have just opened to pollinate the female flowers. The female flower is pollinated by 2 male flowers; the method for preventing sunburn is as follows: in the fruit expansion stage, use newspapers to fold into an inverted funnel shape and cover the melon ...

Embodiment 3

[0033] A kind of seed retention method that present embodiment improves wax gourd seed germination rate, comprises the following steps:

[0034] (1) Management and harvesting of melon seeds: daily management is carried out according to the normal growth requirements of plants during the growth period of melon seeds, to prevent sunburn, and the vines of melon seeds grow for 60 days during the whole growth period of melon fruits, and then the vines are harvested; the daily management Including: cut off all the side vines on the main vine from the vine drawing stage to the flowering stage, and only keep a thick main vine, and manage it with a single vine and a single melon; when the flowers are in full bloom, take the male flowers that have just opened to pollinate the female flowers. The female flowers are pollinated by 3 male flowers; the method for preventing sunburn is as follows: in the fruit expansion stage, use newspapers to fold into an inverted funnel shape and cover the ...

Abstract

The invention discloses a seed reserving method capable of increasing the germination rate of white guard seeds and relates to the technical fields of seed production and reservation of melons and fruits. The method comprises the steps: growing melon fruiting vines in the whole growing period of seed melon fruits for 50-60 d, then, cutting off the vines, and carrying out harvesting; carrying out after-ripening treatment on the harvested seed melons for 15-25 d, then, cutting the melons, simultaneously placing seeds and seed cysts into a nonmetal vessel with an opening, and retting the seeds for 12-24 h; and washing seeds, and drying the seeds in the sun until the water content is smaller than or equal to 8%. The method disclosed by the invention aims at solving the problems that the current novel white guard seeds are low in germination rate and more labor and time are wasted or operation is difficult due to the adoption of seed knocking, temperature-change treatment or agent treatment; by after-ripening the seed melons, regulating a seed extraction process and finding a simple and feasible freshly-harvested white guard seed reserving method, the germination rate of the novel whiteguard seeds is effectively increased, the seed breeding progress is accelerated, and the production of the white guards is promoted; and the seeds obtained by using the seed reserving method are shallow in dormancy, pretreatment is not needed, and the relatively high germination rate can be obtained.

Description

【Technical field】 [0001] The invention relates to the technical field of melon and fruit seed production and reservation, in particular to a seed reservation method for increasing the germination rate of wax gourd seeds. 【Background technique】 [0002] Winter melon is one of the main vegetable varieties in South China and East China, with a wide range of cultivation areas and a large demand for seeds. Freshly picked seeds of wax gourd are dormant, and the general dormancy period is about 80 days. Direct germination before sowing will cause low germination rate, slow germination, and irregular germination, which will affect the breeding, sales and production of later seeds. Therefore, wax gourd seeds need to be pre-treated before germination to break dormancy and increase germination rate. Commonly used pretreatment methods mainly include: breaking the seed coat (commonly known as "knocking" or "breaking the shell"), variable temperature treatment, and chemicals (such as: hy...
