Cultivation technology of multi-fruit high-yield large watermelon

Abstract

A cultivation technology of a multi-fruit high-yield large watermelon can resist continuous cropping; fruits are easy to bear; and the watermelon cultivation technology can save effort and labor and increase the yield. The technology is characterized in that the ground is digged in autumn and irrigation is performed in winter, 10-45 tons of organic fertilizer, 100-150kg of matured soybean, 250-300kg of diammonium, 150-200kg of urea, 200-300kg of potassium sulfate and 300-350kg of calcium superphosphate are applied per hectare before cultivation, 20% of the fertilizers are applied again in continuous cropping; after the fruits are grown, the tops are not removed and pruning is not performed to ensure that the watermelon can grow naturally, fruit-expanding fertilizers, namely urea and potassium sulfate are applied per hectare; and rare earth micro-fertilizer is sprayed onto the leaves in the medium / late stage of fruiting for 2-3 times. The yield is 160-210 tons per hectare, which is 2-3times of the traditional cultivation method and creates a new record of watermelon yield. By adopting the cultivation technology, the cost can be reduced, land resources can be saved, the utilizationrate of land can be increased and the economic benefit can be increased; the watermelon is convenient to store and transport, is big and has good mouth feeling; and in the experiment of the invention, 63 fruits which are 544.5kg in all can be obtained for the Jilin Taonan Heilongjiang River watermelon and the biggest fruit is 57.5kg. The cultivation technology is suitable to be used in the cultivation areas of the first-filial generation Hong guanlong and the like.

Description

technical field [0001] The invention relates to a cultivation technique for agricultural melon and fruit crops, in particular to anti-heavy stubble and easy fruit setting. After the fruit is set, it does not need to be pinched or branched, and it is allowed to grow naturally, which is worry-free, labor-saving and high-yield; it can increase the weight of a single fruit Or a kind of multi-melon high-yield large-fruit type watermelon cultivation technique of one strain of output multi-melon, special multi-melon. Background technique [0002] Watermelon is an annual vine herb of Cucurbitaceae. Watermelon is the king of melons and one of the most common fruits. Because it was introduced from the Western Regions in the Han Dynasty, it is called watermelon. At present, except for a few remote and cold areas, it is planted all over the country, and it has been cultivated in my country for hundreds of years. Watermelon is crisp, tender and juicy. It is a good product for relieving ...

Problems solved by technology

With the continuous expansion of watermelon cultivation area, continuous cropping is inevitable, so the continuous cropping obstacles of watermelon production are very serious, and the yield and quality are greatly reduced.

Continuous cropping of watermelon often results in unbalanced soil nutrients, hindering the growth of watermelon; decreasing the beneficial microbial flora in the soil, increasing the accumulation of pathogenic bacteria, and aggravating soil-borne diseases

At present, chemical agents are often used to prevent watermelon continuous cropping obstacles, but the control effect is not satisfactory; and long-term use of chemical agents in large quantities will lead to resistance of pathogenic bacteria and a series of problems such as pesticide pollution, which will cause serious damage to human health and the environment. The problem
