A greenhouse cultivation and management method for multi-harvest and high-yield watermelons

Abstract

The invention discloses a greenhouse cultivation and management method of high-yield watermelons growing with multiple crops in one year. The method is characterized in that the greenhouse technology is improved; the planting distance ratio is made to be reasonable; the continuous fruit setting technology is adopted, vegetative growth and reproductive growth are adjusted, watermelon fruit setting and watermelon seedling growth are controlled, the fruit setting number and the weight of a single watermelon are increased, and the yield per plant is guaranteed; nutrient and water management is conducted, wherein base fertilizer is applied to the whole layer, organic fertilizer and inorganic fertilizer are combined, nitrogen fertilizer, phosphorus fertilizer, potassium fertilizer, calcium fertilizer and magnesium fertilizer are in coordination, topdressing is conducted after watermelons are harvested, the amount of fertilizer is determined according to the yield, drop irrigation is conducted with a small amount of water, and water and fertilizer are combined. Compared with the prior art, the cultivation and management method has the advantages that high yield and high efficiency are achieved, under the condition that watermelons can be produced and supplied all year around, two times to three times of seedling culture, two times to three times of field plantation, seedling management, field operation and other operations can be omitted, and seedling planting cost, labor cost and the like are lowered.

Description

technical field [0001] The invention relates to a watermelon cultivation technology, in particular to a watermelon greenhouse cultivation management method with multiple crops and high yield. Background technique [0002] Watermelon is an annual vine herb of the family Cucurbitaceae. It can be called the king of melons. It is one of the more common fruits and plays an important role in people's lives. At present, except for a few remote and cold areas, it is planted all over the country. There are hundreds of years of cultivation history. The traditional cultivation methods are spring, summer and autumn cultivation. Due to the heavy rain in summer and the heavy pests and diseases, only one crop can be harvested. Under the low temperature and rainy climate, not only the growth is poor but also the pests and diseases are easy to be induced. For a long time, watermelons are planted in different seasons, spring, In summer and autumn, seeds are sown and seedlings are raised resp...

Problems solved by technology

The traditional cultivation method is spring, summer and autumn cultivation. Due to the heavy rain in summer and the heavy pests and diseases, only one crop can be harvested. Under the low temperature and rainy climate, not only the growth is poor, but also the pests and diseases are easy to be induced. For a long time, watermelons are planted according to seasons, spring, In summer and autumn, sow seeds and raise seedlings separately, and produce one crop of melons each season. The production cost is high, labor-intensive and time-consuming, and the economic benefit is low.

Cultivation in facilities such as greenhouses can overcome unfavorable climatic conditions such as open field cultivation, but it cannot yet achieve the goals of high quality, high yield and high efficiency.

Judging from the current research progress, generally only focus on keeping the greenhouse warm, the ratio of fertilization amount to N\P\K, without considering the influence of greenhouse construction, field layout, planting density, and changes in later fertilization structure on yield. In addition, there are few researches on the prevention and control techniques of the major soil-borne disease Fusarium wilt and the new pest Bemisia tabaci
