According to a recent report from the Guizhou Provincial Agricultural Meteorological Center, due to the continued low temperature in the first half of March and the previous period, the growth period and fruit tree flowering period of Guizhou wheat rape were generally postponed. Experts suggested that measures such as strengthening field management should be taken to respond actively. According to the monitoring statistics, in March this year, the average temperature in the southern margin was 12.1 to 16.8 °C, and the rest of the region was 6.7 to 12.0 °C. The majority of the western region and the south of the central region were normal compared with the normal years (except for Panxian and Xingyi). The rest of the area is 0.5 to 2.5 °C lower. The monthly precipitation is mostly in the eastern part of the province, the central part and the red water are 50.1 to 167.3 mm, the northwestern margin and the southwest are 11.6 to 30.0 mm, and the rest are 30.1 to 50.0 mm, and most of the southwestern Guizhou and Bijie areas. The central and western parts of Zunyi and Jianhe are 2 to 70% less than normal, and the rest are 1.2 to normal.
Affected by this, most of the province's growth period from the jointing to the heading period was postponed for more than 5 days. The growth period of rapeseed in most of the province was generally delayed by more than 10 days.
Experts suggest that April is the key period for the formation of rapeseed and wheat. It is necessary to strengthen the field management to apply panicle fertilizer and granular fertilizer as appropriate, and promote the accumulation of dry matter. All localities should pay close attention to planting and breeding, and the central and western regions should adopt the method of double-membrane dry breeding. In order to cope with the adverse effects of persistent low temperature on flue-cured tobacco seedlings in the early stage, all localities should prepare for the transplanting of seedlings under the membrane to ensure timely transplanting of flue-cured tobacco; it is necessary to pay close attention to the weather forecast of local meteorological stations and actively carry out lightning and hail disasters.
