Fruit and Vegetable News Editor: You are good! I am a subscriber of your magazine Shandong Weifang. Seedless watermelon is high in sugar content, strong in disease resistance and moisture resistance, high in yield and stable in production, and resistant to storage and transportation. It can be stored indoors for 1 month at room temperature, and its price is 1/3 to 1/2 higher than that of normal watermelon. The majority of growers and consumers favored, but I do not know how to grow seedless watermelon? Weinan Changle County, Liunan Chun Liu Jianchun: Hello! To master the seedless watermelon cultivation techniques, it is necessary to first understand the difficulties and priorities in the production of seedless watermelons. Seedless watermelon treats diploid watermelon with a solution called “colchicine†and doubles the number of chromosomes in the cell to a tetraploid watermelon, then uses a tetraploid watermelon as a female parent and a diploid watermelon. The triploid watermelon obtained as a parent for crossbreeding was pollinated with pollen of diploid (or tetraploid) watermelon on the stigma of the triploid watermelon plant. The obtained fruit was triploid. Seed watermelon. The greatest feature of triploid plants is the vigorous growth of plants and the need to configure pollination varieties. The main growth and development of seedless watermelon is basically the same as that of ordinary watermelon, but its characteristics in morphology and physiology are obviously different from that of ordinary watermelon. The main manifestations are as follows: Seed coat is thick, germinal development is poor, and seed germination is difficult. The solution: 1 broken shell germination. Comparable not broken shell germination to improve the germination rate of 3-4 times; 2 high temperature germination. In the 32 °C -35 °C conditions, can promote its rapid budding; or with 55 °C water soaking 4-6 hours, if the shell is soaked after about 2 hours; 3 control humidity. Seedless watermelon germinates weakly, humidity is easy to cause rotten seeds, so controlling humidity and increasing ventilation conditions is the key to seedless watermelon germination. Germination can use sand dishes and other methods to control humidity and improve ventilation conditions. Seedlings grow weakly and slowly, and seedlings are more difficult. Solution: It is necessary to strengthen the control of temperature, humidity, light, gas and other conditions during the seedling stage, as well as the management of fertilizer and water, so as to promote the rapid and normal growth of seedlings. Since the male flower pollen grains of seedless watermelons have no viability, they cannot be used to pollinate the ovary development of female flowers. At the same time, its growth tends to prosper and it is difficult to set fruit. Solution: When seedless watermelons are cultivated, they should be equipped with excellent diploid watermelon cultivars to ensure good pollination and pollination. In general, planting pollination varieties and seedless watermelons should be arranged at the ratio of 1:15-20. Seedless watermelon planting slow seedlings, through fertilizer, water, temperature and other conditions, the appropriate control of plant growth potential, while timely pruning pressure vines and other work in order to avoid lengthy, to ensure normal sitting melon. Because the triploid seedless watermelon is both a polyploid and a hybrid, it has strong growth and strong resistance. It needs a large amount of fertilizer and water, and the melon farmers call it “the big belly man who can eat and drink†and describe it vividly. It's this feature. Solution: After seedless watermelon is set, the growth of the plant begins to change from vegetative growth to vegetative growth and reproductive growth. It is no longer dangerous and can be reused to promote fruit enlargement and plant growth, and increase fruit set in the later period. It has been observed that triploid vines can sit on two fruit at the same time, and can normally enlarge, and the fruit setting rate is still high in the later period. It can be seen that strengthening late-stage fertilizer and water management is of great significance for the development of triploids. In short, the amount of fertilizer for seedless watermelon should be 10-20% higher than that of ordinary watermelon. When the melon grows, it is necessary to appropriately control the supply of fertilizer and water in order to increase the soluble solid content of fruits and achieve the effect of improving quality. To sum up, to plant a good triploid seedless watermelon, we should start from the familiar with its fertility characteristics (tight, weak, difficult to set fruit, and great potential), and then to take these characteristics, cultivation to take the appropriate The integrated measures such as “scratching melons†and “post-promoting†can make full use of the effect of increasing the output of seedless watermelons.
