Applying boron fertilizer to prevent and cure watermelon hollow

There are many reasons for the thick and hollow watermelon rind, which are mainly related to climate and fertilization techniques. The measures for prevention and control of watermelon hollow thick skin are described below:

Increase boron fertilizer. Watermelon has a short growing period and a large amount of growth. Therefore, watermelon needs a large amount of fertilizer, and the use of organic fertilizer and chemical fertilizer must be reasonably coordinated. Generally dominated by organic fertilizer (80%), supplemented by chemical fertilizers. Basic fertilizer should be the base fertilizer, accounting for 60% to 70% of the total fertilization, supplemented by top dressing, accounting for 30% to 40% of the total amount of fertilizer. After testing, borax can prevent and cure hollow disease, and increasing the amount of boron fertilizer can make the transportation of nutrients unimpeded reach the fruit and become a thin, solid, high-quality melon. 100 grams of borax per acre with melon fields, first dissolved with a small amount of hot water plus 50 kilograms of fresh water, before the flowering of watermelon to the foliage spray 1-2 times, can also be applied to the hole in the cultivation of watermelon suitable for borax, per acre With borax 1 ~ 1.5 kg. During fruit enlargement, watermelon often ends prematurely due to lack of water and enters the mature stage. As a result, the cells are not enriched, causing the cell wall to rupture, resulting in hollow watermelon. It should generally be grasped that watering before sitting is small and the number of times is small. Increase the amount of watering and increase the number of watering after the melon recoil, every 3 to 5 days, 1 irrigation, furrow irrigation, gradually increasing from less to more, must not be eager to achieve, until the watermelon mature 5 to 7 The sky can stop.
