One-seed multi-crop cultivation method of small fruit type watermelon

Abstract

The invention discloses a one-seed multi-crop cultivation method of a small fruit type watermelon, relating to the technical field of watermelon cultivation. The one-seed multi-crop cultivation method comprises the following steps of: (1) selecting a small fruit type watermelon variety to carry out protected cultivation and using single-vine or double-vine type whole branch to carry out production; (2) immediately additionally fertilizing a compound fertilizer for one time after harvesting a watermelon so as to accelerate a plant root adventitious bud to grow out a new watermelon vine; (3) when the new germinated vine grows up to above 20 cm long, timely pruning an old fruited vine, carrying out foliar fertilization to accelerate the healthy and strong growth of a new watermelon vine and carrying out production and harvesting again; and (4) repeating operation steps (2) and (3) to carry out the production and harvesting of at least four crops of watermelons totally. According to the cultivation method, one-seed multi-crop can be realized, and the purposes of cultivation links decrease, high yield, high efficiency and long-season cultivation can be achieved.

Description

technical field [0001] The invention belongs to the technical field of watermelon cultivation, and in particular relates to a multi-crop cultivation method of a small fruit type watermelon. Background technique [0002] Watermelon ranks fourth among the world's top ten fruits and occupies an important position in the world's horticultural industry. my country is a big producer and consumer of watermelons, with an annual harvest area of ​​2.2125 million hectares, and the production area and consumption account for more than 1 / 2 of the world's total (Sun Xiaowu, Zhang Xian, Ma Yue, etc. Research and Application of Seedless Watermelon in China . Beijing: China Agricultural Press, 2009). Therefore, watermelon, as an important high-efficiency economic crop, plays an important role in the adjustment of the planting industry structure in our country and the promotion of farmers' wealth and income. [0003] Watermelon is a crop that likes temperature, light, and water, but is afrai...

Problems solved by technology

Xiao Guanghui discussed the regenerative cultivation technology of small fruit type watermelon (Xiao Guanghui. Early spring facility regenerative cultivation technology of small fruit type watermelon. Changjiang Vegetables, 2011(1): 13-15). The contribution of this study is that the small fruit type Watermelons are cultivated in protected facilities in early spring. After the first batch of watermelon is harvested, the old vines are cut off at the 4-5 nodes at the base of the plant. Timely watering and topdressing promotes the latent adventitious buds at the base of the plant to germinate and grow new melon vines. The effect of stubble; its defect is that this regenerative cultivation technique cuts off the old vines immediately after the watermelon is harvested, and the growth balance relationship between the above-ground part and the underground part of the watermelon plant is suddenly destroyed, which accelerates the senescence of the root system, and its growth and absorption The decline in capacity leads to slow germination of latent adventitious buds at the base of watermelon plants, weak growth of pumped adventitious vines, and some individual aging plants even die early, and can not produce adventitious vines. Yield of head stubble melon is much lower

In addition, this regenerative cultivation technique only realizes a kind of double-cropping
