First of all, the hot weather continues and consumer demand is strong. High temperature weather lasts for a long time, which makes the demand for summer-relieving melons, especially watermelons, strong, and the sales volume in many markets will rise rapidly, which will lead to the shortage of watermelons in the market, thus leading to the phenomenon that merchants go to the production areas to replenish goods on a large scale.
In addition to the increase in consumption in hot weather, there is another reason why the price of watermelon in producing areas has been rising all the way. Extreme weather in some areas has affected the yield of watermelon. Cao Dongbo introduced that in Dali, Shaanxi, Qingzhou, Shandong and other areas, extreme convective weather and hail disasters occurred, which caused the yield of watermelon in the arch shed to decrease, which further aggravated the shortage of watermelon in recent days and led to an increase in melon prices.
Matters needing attention in watermelon planting
Fertilizer is the material basis for high yield of watermelon, especially in the early stage of growth, the growth cycle of zucchini is short, the plants grow fast, and it is inconvenient to apply fertilizer after film mulching. Insufficient application of base fertilizer is easy to cause premature aging, which is not conducive to increasing production. Therefore, in the production of early-maturing watermelon, the "one-shell" fertilization method is advocated when applying base fertilizer. 90% fertilizer should be used as base fertilizer.
When applying base fertilizer, organic fertilizer is the main fertilizer, and nitrogen, phosphorus and potassium are applied to ensure a balanced supply of nutrients. Promote plant growth and coordinate growth. Generally, about 5000 kilograms of decomposed organic fertilizer can be applied per mu, and about 30 kilograms of ternary compound fertilizer of nitrogen, phosphorus and potassium can be applied in combination with soil preparation.
