Ji'nan nearly 500 thousand acres of farmland affected by corn per mu of up to 300 yuan.
Li Yongming Intern of the Ji'nan Times journalist Wu Yong for
preliminary statistics, 17 days of rain has caused nearly 1/10 of the city's farmland disaster, of which the main crops are corn. The heavy rainfall caused the accumulation of water in some plots, which affected the normal growth and development of maize, and the water accumulated in a few regions could not be eliminated in time. The phenomenon of dead seedling and sterilization appeared in the field.
reference to the influence of flood to maize, the relevant people of the agricultural sector introduced that the current maize was in the middle period of growth and development, the maize was in the middle growth period, and the direct seeding maize was in the late jointing period, which was more sensitive to the waterlogging reaction.
post disaster plots are not hopeless. Ji'nan's agricultural sector has formulated the "technical advice on disaster prevention and mitigation of maize". The affected farmland areas are divided into 3 categories to guide them. Even if some of the corn after the disaster has died, planting silage corn and other crops can be reliably planted in the short term. When the feed is sold to the dairy farm, it will earn seven hundred or eight hundred yuan per mu.

planting short term crops in a short period of water accumulated in a short time. The silage corn or vegetables such as cabbage, rape and autumn radish should be planted in time.
silage corn: special silage corn for planting. It was sowed in early August and stored as ensiling at the beginning of October.
Chinese cabbage: after autumn, it is necessary to select early maturity varieties with short growth period, good quality, virus resistance, downy mildew, and soft rot resistance. Production should be based on heavy base cultivation and high ridge cultivation. In general, 3000-4000 kg of organic fertilizer and 40-50 kg of diammonium phosphate are applied per mu.
rape: planting in autumn, usually sowing in August, harvest in 9-10 months, and pay attention to prevention and control of downy mildew, black spot, anthrax, aphid, rapeseed, Plutella xylostella and other diseases and pests.
autumn radish: Autumn radish should be planted in the middle of July at the middle of -8. Suitable varieties with short growth period, high yield, strong resistance and good quality should be selected.
vegetable production should pay attention to order production or arrange different sowing dates, so as to prevent large quantities of vegetables from going on sale and affecting sales.

land which can not be discharged in a short period of time, should be ploughed and dried in time when large machinery can be laid down to ensure that the sowing and growth of wheat are not affected. Because of the long accumulation of water in the land, the beneficial microbial flora of the soil has been destroyed very much, and the soil slate is serious. If the deep ploughing is not carried out in time, it will be bad for the growth of the next season wheat.
yield reduction plot >
reduction plots refer to the plots where crop yields have not been reduced after flooding.
1. timely drainage: after rain, we should eliminate the accumulated water in time and minimize the losses caused by the disaster. Arrange ditches, ensure smooth drainage, and prepare for future continuous rainfall.
2. timely Cultivation: on the basis of grasping drainage, timely cultivation is carried out to prevent soil hardening, ventilation and moisture dissipation, and promote root growth and development.
3. top dressing: 10-15 kg of urea per mu, promoting maize growth and development. Foliar spray of nutrient solution such as urea, potassium dihydrogen phosphate and other growth regulators.
4. in time to prevent and control diseases and insect pests: maize, which is suffering from waterlogging, should especially strengthen the prevention and control of pests and grass, so as to reduce the harm to corn as much as possible and ensure the growth and development.
5. harvest period should be done well in the harvest period of corn: due to continuous rainfall, the growth of corn is bad and the harvest period can not be mature. [general field]
general field refers to the plots where water can be discharged in time and crops can grow normally after flood.
1. disease and pest control: when growing to 9-10 leaves, it can prevent and control the armyworm, corn borer and so on in time, and can be used to prevent and cure with Phoxim and chlorpyrifos. The middle and late period of maize is the key period of yield formation, and it is also the period of concentrated occurrence of many diseases and insects. It should be widely used to prevent and control many diseases and insect pests in middle and late period of maize, and reduce the number of panicle insects in the later period. It can be controlled by mixed spraying of thiazide, high chlorine fluorine and microcapsule suspension.
2. fertilizer management: in the middle and late growth, it is timely to apply panicle fertilizer to promote the differentiation of young spikes and small flowers, and to ensure the panicle, panicle, and grain. Generally, 15-20 kg of urea is chased.
3. other management: strengthening cultivation and weeding to reduce the occurrence and spread of diseases and insect pests.
