Recently, the rainfall in Liaocheng, Shandong Province is frequent, and the rainfall is significantly higher than that of the normal year. Many areas suffer from flood disasters, and some fields have serious water accumulation. In response to the problem of farmland after heavy rain, the Liaocheng Agriculture Committee organized experts to write “Technical Measures for the Classification and Management of Disaster-Resting Farmland,” and actively launched agricultural technicians at all levels to drill down into Datian for technical guidance.

The Agriculture Committee of Liaocheng City reminded them of continuing to collect stagnant water and field plots, and would like to drain water in any way. After the planting, it will be done in time for soil preparation, such as lettuce, spinach, and rapeseed, as well as Chinese cabbage and other crops. The water in the field lasts for more than 3 days. The yellowing of the lower leaves of most crops after the row of crops affects the process of plant growth and development. The time for cultivating and cultivating the ploughs should be taken into account and the available nitrogen fertilizer should be increased by 10-15 kg per acre. After the weather is fine, pest control should be carried out in time, fungicides and insecticides should be applied, and foliar fertilizers such as potassium dihydrogen phosphate should be sprayed.

With continued high temperatures, rice fields are also thirsty. Since late July, moderate and severe high-temperature heat damage has occurred in most of Hubei Province, which has caused serious impact on the heading and flowering of medium-sized rice in Jianghan Plain.

At present, the majority of middle rice in Hubei Province has entered the heading and flowering stage. During this period, temperatures above 35°C for three consecutive days will cause high-temperature heat damage to rice, resulting in poor young ear differentiation, poor flowering and pollination, and reduced number of grains per ear. The fertility rate decreased and the final production was reduced. In order to reduce the damage caused by high temperature and heat damage to farmers, Guo Ziping, director of the Hubei Provincial Agricultural Technology Extension Station, suggested that the main rice production areas should be well treated with drought irrigation, deep water irrigation in the field, and 6 to 10 cm water layer should be maintained. Night row, reduce the field temperature; at the same time, with 150 ~ 200 grams of potassium dihydrogen phosphate or 0.5 ~ 1 kg of urea mixed with 60 kg of water for early and evening foliar spray fertilizer, enhance rice's own resistance, reduce heat damage, improve seed setting rate and Thousand grain weight.

He also suggested that the cotton producing areas should divert water from furrow irrigation in time to improve the microclimate of the farmland, and timely apply flower and bell fertilizers to prevent the premature decline of functional leaves. The summer corn planting area should adopt sprinkler irrigation to improve the field microclimate, increase air humidity, and lower the temperature. Beware of “spraying flowers”.

In Anhui, a high temperature of 35°C or more occurred from July 23, with the daily maximum temperature exceeding 37°C in most parts of the south of the Huaihe River. As sunny and hot weather continues, the crops are in a period of vigorous growth. The evaporation and evapotranspiration of the farmland are accelerated, the loss of soil is accelerating, and the drought in some areas appears, affecting the growth of crops.

The Anhui Provincial Meteorological Science Research Institute agricultural gas business personnel reminded the farmers to do a good job in field management. Coping with suggestions and measures include mainly diligent irrigation of shallow rice, daily irrigation at night, timely drying, and improvement of the microclimate in the field; early rice should be caught in clear weather to seize and beaten, and should be returned to the warehouse in time; late rice transplanting should be arranged as much as possible. In the morning and evening, after transplanting, it is necessary to pay attention to water temperature adjustment to prevent high-temperature burning seedlings and promote the development of returning green; strengthen cotton field management, pruning and squatting in order to maintain good ventilation and light conditions, reduce cotton buds boll off; sunny heat temperature It is easy to cause fruits and vegetables to fall and fall. Use a shade net to cover the temperature and water properly, but avoid watering at high temperatures in the afternoon.
