First, the formation of courgette "short cob" is related to poor flower bud differentiation of Zucchini. Due to the low temperature in the greenhouse, low ground temperature, weak light, poor ventilation and light transmission, low leaf photosynthetic efficiency, and less nutrient accumulation. Coupled with the decline in the root function of Zucchini, the absorption, transportation, and utilization of fertilizer and water are hindered, resulting in poor flower bud differentiation of Zucchini. Second, in the fruit development process of zucchini, point anther concentration is too large, anther too early, easily lead to abnormal development of Guatemala; stay Guaduo, not sparse melon, resulting in melon strip nutrition, its growth and development will be inhibited , "Short melon" prone to happen; water, hypertrophy, roots, water absorption, absorption capacity decreased, Zucchini on the ground part of the fertilizer and water supply is not sufficient, but also easy to make melons deformed. Therefore, vegetable farmers should take corresponding preventive measures based on the above reasons: 1. Before planting, the base fertilizer is mixed with farmyard manure (chicken manure, duck manure) about 20 square meters and ternary compound fertilizer 150 kilograms or so. The long-term accelerated effect can meet the nutrient requirements for growth and development of the whole growth period of summer cucurbits. During colonization, antibacterial 968 seedling trees were planted through the acupuncture points (80 to 120 kg/mu), coordinated plant growth, and cultivated strong seedlings and strong trees, which laid the nutritional foundation for the differentiation of flower buds of Zucchini. 2. In early spring, special attention should be paid to the point that the concentration of anthers should not be too large. It can be prepared by first using naphthalene acetic acid 5 g + gibberellin 0.5 g + melon swelling agent 5 g + borax 20 g + glucose 50 g + water 500 ml The original liquid, then take the prepared liquid 5 ml + potassium dihydrogen phosphate 10 g + urea 10 g + acetaminophen 5 g + water 500 ml, fully miscible and use a writing brush to carry the melon melon. 3. Zucchini sitting on the melon, on the one hand, pay attention to the greenhouse insulation, add light. The daytime temperature is maintained at 20-22°C and the nighttime temperature is 12-14°C. Wipe the shed film in time, pick up the leaves and hang the vines to increase the ventilation and light transmission between the plants; on the other hand, administer 6?8 kg/mu to promote fruit attack (20?10?30). Surface spraying potassium dihydrogen phosphate 500 times mixed polyboron 1500 times. Anticancer, it can arrest the proliferation of malicious cell, which will prevent arthritis and other diseases.
