Greenhouse cultivation method for small-size watermelons

Abstract

The invention discloses a greenhouse cultivation method for small-size watermelons. The greenhouse cultivation method comprises the following steps of: firstly, growing seedlings in a seedling tray; planting watermelon seedlings growing to two leaves and one core to the inside of a greenhouse; and controlling water and fertilizer in the growing process of the watermelon seedlings to ensure that the watermelons are better grown and developed and fruit setting rate and fruit quality are improved. In the whole production process, water is applied by adopting a drip irrigation mode and soil at roots of plants is always kept wet, so that the demand of plants on water is met and the waste of water resources is avoided; at stem growing phase, fertilizer is applied by adopting a drip irrigation mode, so that the water and the fertilizer are simultaneously applied, more traditional work procedures of separately irrigating and applying fertilizer and pesticide are omitted, work amount is reduced, work efficiency is increased and utilization rate of the water and the fertilizer is increased; the greenhouse can play a role of an insect-proof screen, so that insect pests are reduced; and the plants are reasonably pruned at the steam growing phase, the flowering phase and the expansion phase, so that the fruit setting and the fruit quality are improved.

Description

technical field [0001] The invention relates to a watermelon cultivation method, in particular to a small-sized watermelon cultivation method in a greenhouse. Background technique [0002] Watermelon is a popular product for relieving summer heat and quenching thirst. With the improvement of people's living standards, higher requirements are put forward for the color, variety, quality and flavor of watermelon. Traditional watermelon products are all large varieties of 4-6kg. In recent years, a new variety of small-scale watermelon weighing 1.5-2.0kg has come out. Representative varieties such as early spring Hongyu, the cultivation area is expanding year by year. The meat of the small watermelon variety is tender and crispy, juicy and melts in the mouth, the sugar in the center reaches 12-13 degrees, the flavor is elegant, and the quality is excellent. The growth characteristics of small watermelons are different from those of large watermelons, but the current cultivation ...

Problems solved by technology

The growth characteristics of small watermelons are different from those of large watermelons, but the current cultivation methods of small watermelons are mainly based on the continuation of the cultivation methods of large watermelons, which has affected the fruit quality and yield of small watermelons.

In the traditional watermelon cultivation methods, irrigation methods such as furrow irrigation, flood irrigation or artificial watering all have the disadvantages of low water resource utilization efficiency, labor and time-consuming
