According to the statistics of the agricultural sector, the whole district of Guangxi has basically completed the work of harvesting and drying rice. As of October 29, the region had received 1,085,600 mu of late rice, accounting for 7.10% of the area of ​​late rice, which was 880,100 mu slower than the same period last year. All cities in the district have been reclaimed, and the harvest of late rice in Guilin is the fastest. It has received 435,600 mu of late rice, accounting for 25.07% of the area of ​​late rice. The region has received 2,078,800 mu of medium-sized rice, accounting for 96.11% of the real-estate area. It has received 1,384,700 mu of mid-late corn and 815,000 mu of mid-late soybeans.
The area of ​​winter crops in the region is 4,595,200 mu, which is 31,500 mu slower than the same period of last year. Among them, the food crop is 358,500 mu, which is slower by 94,600 mu; the rape is 279,700 mu, which is 264,900 mu; the winter plant is 2,766,300 mu, which is 364,700 mu; the other crops (green manure, green fodder, etc.) are 1,284,700 mu. The year-on-year slow was 318,200 mu. The development of autumn and winter vegetables is accelerating, and the area of ​​pollution-free vegetables is over 60%. The region has planted 683.18 million mu of autumn and winter vegetables (including horseshoes, edible fungi, etc.), which is 285,300 mu. Among them, there are 451.44 million mu of pollution-free vegetables, accounting for 66.08% of the autumn and winter vegetables. Among the vegetables that have been planted, the leafy vegetables are 249.37 million mu of cane and fruit, 82.60 million mu, the melons are 470,800 mu, the beans are 649,700 mu, the root vegetables are 69.46 million mu, the aquatic species is 307,700 mu, the yam is 20.62 million mu, and the other is 1,183,200 mu. The progress of rapeseed and green manure cultivation is relatively slow. Due to the slow progress of late rice insertion this year, affecting the harvest progress of late rice, the cultivation progress of rapeseed and green manure is slower than that of the same period last year. It is understood that most of the current rapeseed is in the nursery period, and only a large amount of transplanting began in November. As of October 28, the region has planted 279,700 mu of rapeseed and 1,094,400 mu of green manure, a year-on-year decrease of 266,900 mu and 306,700 mu.
The meteorological department expects Guangxi to be cloudy to cloudy in the past two days. Nanning City: Today day to night, sunny to cloudy, northeast wind 1-2, the highest temperature of 26 ° C, the lowest temperature of 16 ° C. The meteorological conditions are generally favorable for autumn harvesting. (Illustration)
Future Agricultural Suggestions:
1. Continue to strengthen the field management of late rice in the late stage, and keep the rice fields dry and wet until yellow ripe to prevent premature senescence of the plants.
2, grasp the harvest of mature rice, corn, soybeans and other autumn harvest crops to ensure that the particles return to the warehouse.
3. Actively do field management of autumn and winter crops. Grasp the current favorable opportunity to prepare the land and plant in time; for the autumn and winter crops that have been planted, timely manage the fields such as cultivating, weeding and fertilizing to promote the robust growth of crops.
4. Harvest mature citrus, banana and other fruits at the right time. After harvesting the fruit, pay attention to the classification, grading, packaging, etc., in order to facilitate transportation and increase the listing price. In addition, the water and fertilizer management of the orchard and the prevention and control of pests and diseases should be done in time to facilitate the recovery of the tree.
