Embodiment

[0014] Select seedless watermelon (combination) 'Heiyufeng' and small seedless watermelon combination early-growing Daxiong (small fruit type) for seed production respectively, including the following steps:

[0015] 1 Selection of planting land

[0016] 1.1 Site selection conditions

[0017] Conditions for seedless watermelon planting selection: ① Select plots that have not grown melons and vegetables for more than 5 years. ②The soil layer is deep (the surface layer is sandy loam and the bottom layer is loam soil), loose and fertile, convenient for drainage and irrigation, good ventilation, and sufficient light. ③Soil humus is rich in content and presents aggregate structure. ④ The pH value of the soil is 6.5 to 7.5, and saline-alkali land and land with high groundwater level are not suitable for farming. ⑤ An isolation zone of about 1500m is set up around the production and farming fields.

[0018] 1.2 Soil preparation, fertilization and furrowing

[0019] After selecti...

Abstract

The invention relates to a method for increasing the seed production amount of seedless watermelons, and belongs to the technical field of plant breeding. The method comprises the main technical measures of cutting a main vine in a position, which is 5cm away from the root, of the main vine when the main vine grows to be about 50cm; reserving 4-5 side vines, carrying out cross pollination on 2-4 female flowers of the side vines, wherein the cross pollination can be carried out for once at 8-11 a.m. and once at 4-6 p.m.; wiping off epidermal hairs of young fruits by using soft towel (which is disinfected by alcohol in 75% concentration) when the diameter of the young fruits is 15cm after the cross pollination; spraying CaNO3 of which the concentration is 0.1% to plants and the young fruits for 1-2 times in the morning in a rainy day after 1-2 days of the wiping, reserving 6-10 young fruits in a single plant, and collecting fruits and taking seeds after the fruits are mature. The method disclosed by the invention is simple and easy to realize, the seed production amount of the seedless watermelons per mu can be greatly increased, the land cost is reduced, and the method is suitable for seed production of the seedless watermelons in a large area.

Description

technical field [0001] The invention relates to a method for increasing the seed production amount of seedless watermelon, which belongs to the technical field of plant breeding. Background technique [0002] Seedless watermelon is popular among producers, operators and consumers due to its characteristics of being seedless, high sugar content, disease resistance, high yield and storage and transportation resistance. Therefore, the seedless watermelon industry has developed rapidly in recent years. However, in the production process of seedless watermelon, there are "three lows" problems of low seed collection, low germination rate and low seedling rate. Among them, the main reason for the low amount of seed collection was the decreased pregnancy of the female tetraploid watermelon. The causes of infertility are divided into physiological infertility and functional infertility. Due to the specificity of polyploid organs and other tissue cell structures, the transportation...
