How to avoid watermelon not to melon
The watermelon is covered with vines in fields and field ridges, but there are no watermelons in the field. The causes are as follows: 1. Partial application of nitrogen fertilizer, female flowers will be stunted, easy to cause melons grow long, although flowering pollination, but ovaries thin and dry. Because the growth of stems and leaves consumes too much nutrients, the young melons fall off due to physiological disorders. The lower the fruit-setting node is, the more arrogant the phenomenon is. 2. In addition there are varieties of factors, some of the late-maturing varieties of agricultural production used late seedlings, Dingmiao late, meet the rainy season, the nutritional growth is too strong, it is difficult to sit melon, or late melon, knot small melon. 3. There are also some factors that can lead to fewer melons. Such as: harsh environment, affect the pollen germination. When the air humidity is only 50%, the pollen germination rate drops below 20%; when the temperature drops to 18°C, it is difficult to sit melon; when continuous rain, it causes pollination, insemination, obstruction, easy to "melon melonâ€; inappropriate Spraying pesticides or applying fertilizers outside the roots can also lead to shedding of the young larvae. The planting density is too large, the stems and leaves overlap, and the shade is severe. At the same time, if the young larvae are selected and the diet is too low, malnutrition of the young larvae may cause melons or Poor quality of melons. For the first time, melons should be planted in medium-sized plants with strong fruit set and low sensitivity to temperature, light, and fertilizer. Rational application of base fertilizer. Base fertilizer should be based on decomposed organic fertilizer; to increase phosphorus and potassium fertilizer, reduce nitrogen fertilizer; not excessive fertilization. To properly control the watering of the field, in the growing period of stems and leaves, proper watering is conducive to vegetative growth. In addition, it is not appropriate to spray fertilizer and spray pesticides at the flowering stage to avoid pollen damage. To be closely planted and regulate plant shape. Precocious small watermelon can be properly planted, and the density of medium-maturing watermelon is appropriate to about 500 per mu. Precocious varieties of guaranty should be low, medium-maturing varieties, to remove early female flowers. The melon seedlings growing vigorously, after determining the fruit-holding section, left 5-7 leaves before the holiday, and must pick them up in time.
