The management tasks required for different growth stages of crops are different, mainly the shift of management priorities, and the growth stages of different crop management priorities are different. For the high yield of winter melon, the management of the melon period is very important. . Let's take a look at the management techniques of melon and melon.
Pollination
Winter melon can be artificially pollinated to increase the fruit setting rate. The specific method is to remove the petals and gently apply them on the female flower when the male flower is just opened in the morning. You can also rub the male flower with a cotton swab, then apply a cotton swab to the female flower, or apply the flower handle with 15~20 mg/kg 2,4-D. The pollination time is usually before 8:00 am and no later than 10 points. After pollinating for a day or two, if the male flower falls, the female flower slowly shrinks and the small melon grows up, indicating successful pollination.
2. Remove the side vine
Winter melons grow lateral vines between each petiole and stem, which consumes too much nutrients, so remove the side vines in time to avoid affecting the sitting melon and the melon. Side vines grow faster, and the side vines are usually picked every other day.
3. Topping
After the winter melon is planted with melon, the main vines in the front of the melon maintain 7 to 10 leaves to top the top, which is conducive to nutrient concentration and increase the fruit setting rate.
4. Change head
If the winter melon is too much, the main vine is long and the melon rate is low. When the melon is just growing out, leave 1-2 leaves in front of the melon to kill the top, and then wait for the top vine to grow the vine when you grow the vine, and change it twice, you can sit on the melon.
5. Fertilizer management
After the melon is sitting on the melon, it is necessary to re-fertilize. Generally, about 15 kg of urea can be applied per acre, and the fertilizer is applied once every two weeks. In the middle of the melon, water is usually poured once every 7 to 10 days. In the later stage, water should be poured frequently, and water should be poured once every 5 to 6 days to keep the soil moist.
6. Prevention of pests and diseases
The main pests and diseases of winter melon are powdery mildew, blight and aphids. Powdery mildew is the appearance of polka dots or irregular white lesions on the leaves of melon. In the early stage of the disease, 25% triazolone wettable powder 1500~2000 times solution or 50% sulfur suspension agent 300~400 times solution can be sprayed once every 7 days. Fusarium wilt can be irrigated with 50% carbendazim WP 500 times, once every 10 days, for 2 to 3 times. Aphids can be sprayed once every other week with 10% imidacloprid WP 2000 times.
The above is the focus of the management of melon and melon, and farmers who have planted melon can see if it is useful.
