First, the harm caused by the disaster relief

1. The period of germination and seedling stage of seedling maize during the seedling stage is the period with the greatest influence of alfalfa damage. During this period, the occurrence of larval damage will inhibit the normal physiological activities of the roots due to the lack of oxygen in the soil, resulting in the wilting, yellowing of the seedlings, slow growth, and serious death of the seedlings.

2. The normal physiological activity of the affected root system at the heading stage is reduced, and the roots become dark and rotten afterwards. Leaves gradually chlorosis, photosynthesis decline. The stems are weak and the plants grow slowly. Abnormal growth and development of females and tassels, less tassels branching, delayed silking of the female ear, resulting in no chance of male and female ear flowering, affecting normal flowering and pollination, resulting in a decrease in number of grains, grains, and grains, which may cause serious The whole plant died.

3, flowering period of the victim inhibit the normal growth and absorption of roots, leaves gradually from green to yellow, photosynthetic efficiency is low, the number of grains per spike, grain weight decreased. And due to the decline in plant resistance, will increase the occurrence of sheath blight, stalk rot and other diseases.

Second, post-disaster field management

1. Immediately after the drainage and locust plague occurs, all drainage and irrigation facilities shall be used to quickly eliminate the water in the fields so as to facilitate the plant to resume its growth as soon as possible.

2. The locust plague of planting and supporting plants often causes lodging. If lodging occurs in the early stage, the plants can resume growth on their own. If lodging occurs after the big bell mouth period, the plants can no longer stand upright on their own, and they need to be manually straightened up and hold the soil firmly. Pay attention to cleaning the sludge of stems and leaves so that the leaves can resume growth as soon as possible.

3. After removing the stagnant water in the cultivator field, the cultivator should be cultivated in time to remove soil compaction, spread ventilation, promote root development, and restore the damaged corn as soon as possible.

4. After increasing the available fertilizer, the loss of soil nutrients and the loss of root absorption function caused the corn plants to grow slowly, with yellow leaves and weak growth. In order to restore the growth of the plants as soon as possible, 1% urea and 0.2% dihydrogen potassium may be sprayed on the leaves. After the root system recovers, the roots are topdressed again.

5. After clearing the lower leaves, the humidity in the field after the disaster has caused a large number of corn diseases. To this end, the bottom leaves should be removed to keep the fields airy and transparent, promote evaporation of water in the fields, and reduce the occurrence of diseases.

6, after the destruction of weeds in the field, the soil is wet and it is easy to breed weeds. Weeds should be cleared in time to prevent pests and diseases.

7, after the prevention and treatment of pests and diseases, attention should be paid to the prevention and control of pests and diseases, good pest forecast and prediction, early detection and early prevention and treatment.

8. The promotion of corn after precocious puberty is greedy and late, affecting yield and quality. Workers may be emasculated, the removal of the bottom lobe, and the drying of the loquat leaves after milking, and other measures to promote early maturity of corn. Foliar spray ripening agent can also be used.
