The recent low temperature and rainy weather have had a certain impact on some fruit trees, winter melons and aquaculture in Hainan Province. Unfavorable weather has affected the growth and flowering pollination of bananas and mangoes; the photosynthesis of most melons and vegetables decreased, the growth was hindered, and the melons and vegetables were easy to cause fruit and fruit, the resistance of pests and diseases decreased, and the melons and vegetables were also affected by low temperature and cold damage; The continuous low-temperature and rainy process makes the aquaculture species have slower feeding and growth, and are also prone to disease, which has led to an increase in the price of farmed aquatic products.
According to the meteorological department of Hainan Province, from the 12th to the 16th, the south of Wuzhi Mountain is cloudy with cloudy days and small showers in the local area; the north of Wuzhi Mountain is cloudy with light rain during most of the time. The temperature has risen slowly since the 13th. In the middle of January and late January, cold air activity is still frequent, the average temperature may be lower than normal, and sunshine is less than normal.
Production advice
At present, the low temperature and rainy weather process in some areas may last for 3 to 4 days. In the next 20 days, we still need to focus on the impact of low temperature and low sunshine on the province's agriculture.
1. Pay close attention to the process of low temperature and rainy weather. The winter seedlings in the seedling stage should strengthen the light as much as possible, improve the light and productivity of the seedlings, ensure the normal growth of the seedlings, and appropriately spray the growth regulators in the flowers and fruits to reduce the falling flowers. And fruit drop. In addition, continue to do a good job of warming and warming and disease prevention and control of melon gardens; after the weather is warming up, we should increase the amount of fertilizer to promote rapid growth in time, try to win the winter market and increase the output value.
2. Rainy weather, the growth of rubber trees will be inhibited, it is recommended to stop cutting trees. Weed removal in rubber forests to avoid pests and diseases. In addition, pay attention to the control of the greening and fertilization of the old tree fat points in Jiaoyuan to ensure normal production in the coming year.
3. Banana, "March Red" lychee, etc. Pay attention to prevent cold work and avoid adverse effects of low temperature hazard on production. At present, precipitation in some parts of the southern part of the province continues to be less and less, and it has an adverse effect on the early-maturing varieties of the litchi, "March Red" and mango heading and flowering. The corresponding orchard should pay attention to timely and proper irrigation. After the weather warmed up, the last autumn leaf color of the longan did not enter the green and mature plants, paying attention to the application of foliar fertilizer to promote its timely entry into the relative dormant period to accumulate nutrients.
4. All localities should do a good job of heat preservation of cultured species, and feed them appropriately in combination with the feeding conditions of cultured species. Conventional fish broodstock should be cultured in a special pool. Recently, the intensive cultivation in the early stage has been carried out to increase the fertilizer and promote the development of the gonads to ensure smooth spawning next year. For the New Year's Day, the Spring Festival, and the commercial fish, shrimp and crabs listed in April-May of the following year, it is necessary to raise the special pool, feed the feed regularly, keep the water fresh, promote its protection, and ensure the holiday is safe.
