Fujian will strengthen irrigation and cooling of crops and orchards in late July to ensure water demand
In mid-July, the average temperature in most provinces and cities in Fujian Province was normal or high, the extreme maximum temperature was normal, the sunshine was normal or excessive, and the precipitation was normal or less. The favorable aspect is that the sunny weather is good for early rice harvesting, which is beneficial to the differentiation of young rice spikes, which is beneficial to the growth and transplanting of late rice seedlings, which is conducive to the expansion of longan, citrus, mango and other fruits and the growth of other fruits, and is also beneficial to fruits such as lychee and watermelon. Harvested. The unfavorable aspect is that the hot weather in the first day is high temperature for the unharvested early rice, but since the early rice is in the harvesting period, it has little effect on the yield; at the same time, the high temperature is unfavorable for the photosynthetic growth of dry crops such as sweet potato and vegetables, especially For plots lacking irrigation conditions, crop growth and development are adversely affected.
According to the forecast of the Fujian Provincial Meteorological Observatory, it is expected that the province will be dominated by process weather in late July. Compared with the same period of the previous year, the amount of precipitation in the same period is less in the province. The average temperature in the past is basically normal compared with the same period of the year. The main precipitation period: 21 to 22 days, the weather in the central and southern regions is cloudy to cloudy, and some counties and cities have showers or thunderstorms. From 25 to 27, the weather in the province was cloudy. Some cities and towns in various cities had showers or thunderstorms in the afternoon, and some local counties and cities in the north central area had heavy rain. From 28 to 30, there were showers or thunderstorms in the coastal areas, some of which were moderately rainy, with heavy rains and heavy rains, and the rest of the afternoon with showers or thunderstorms. It is expected to be affected by the subtropical high in the early part of the year. The province will continue to maintain hot weather. The extreme temperatures of 35 to 37 °C in the central and northern parts of the country and 38 °C in the central and northern parts may occur.
Agricultural production advice:
1. It is expected that the province will focus on hot and sunny weather at the beginning of the first year. All localities should pay attention to strengthening the irrigation and cooling of crops and orchards to ensure the water demand of crops.
2, early rice should be collected in time to enter the warehouse, after the receipt of Honda to re-water the plough in time to ensure timely transplanting of late rice. The middle rice is in the stage of young panicle differentiation. It can be seen that the seedlings are reasonably applied to the panicle fertilizer. At the same time, the field leaf area is large, the ventilation and light transmission conditions are poor, and the high temperature weather is easy to induce pests and diseases. Late rice should be transplanted quickly, and it will not be inserted after autumn.
3, the supply of vegetables is about to enter the "autumn light" season, should strengthen the management of alpine anti-season cruciferous and solanaceous vegetables, do a good job in vegetable irrigation, fertilization and pest control.
4, the recent weather is sunny, soil moisture is poor, sweet potato field should strengthen irrigation work, while timely fertilization to promote expansion to ensure the normal growth of sweet potato; "rice-headed potato" should pay close attention to favorable weather time cutting. Autumn soybeans and autumn peanuts should also be planted in time without any mistakes.
5. The orchard under high temperature and heat can take irrigation measures to improve the microclimate conditions of the orchard. When pruning, leave more branches on the sunny side of the tree to reduce the sun. The longan continues to pick up the summer shoots, and the fruit is developing. It is necessary to remove too many summer shoots from the base branches, promote nutrient concentration, and cultivate strong summer shoots, making it a good result for the next year. And pest control work. Litchi should be harvested and fertilized after harvest to help restore the tree and promote the autumn shoots. Citrus is in the period of fruit enlargement, and the summer shoots are continuously pumping. The farming activities are mainly bud and fertilization, in order to promote fruit enlargement and promote autumn shoots, and cultivate the mother branches.
