Planting black skin winter melon in autumn
In autumn, the temperature is high and the weather is dry. Black-skinned melon is vulnerable to thrips. Therefore, we must pay attention to the prevention and control of thrips to protect growth points, young shoots and young melons. The specific control methods are as follows:
During the growth of seedlings and flowering of melons, it is necessary to spray 1500 times 20% thiazole aqueous solution, or 1500 times 25% thiamethoxam aqueous solution, or 800 times 0.3% hydrazine aqueous solution, or 1500 every 10-15 days. 10% by weight of nitenpyram aqueous solution, or 2000 times 20% aqueous solution of spirotetramat, or 1000 times 2.5% aqueous solution of doxorubicin, or 2000 times 40% aqueous solution of acetamiprid, controlled by continuous spraying 3~5 times Spray all the leaves evenly, pay attention to spraying onto the growth point and the young melon, so that it is better to start dropping with water drops.
If it is washed with rain within four hours after spraying, it should be refilled once. Since thrips are prone to drug resistance, the agents should be used interchangeably. Do not use the same agent multiple times in succession. Adding 0.2%~0.3% potassium dihydrogen phosphate aqueous solution and 1500 times 0.001% natural brassinoside to the chemical solution can not only improve the control effect, but also promote the growth of black skin melon.
