The overall situation of wheat oil production in Yancheng this year is generally good, but there are still problems that cannot be ignored. The first is that the seedlings are not balanced and it is difficult to manage seedlings. The total area of ​​the two wheat seedlings was 1,637,400 mu, an increase of 332,000 mu over the previous year, of which 418,000 mu were exuberant, and there were nearly 100 million mu of late-seeding wheat, which made it difficult to manage. The second is that the dry elephant has appeared and the weak seedlings are difficult to transform. Due to the continuous low temperature and little rain in winter, droughts appear in some areas at present. Although the growth of the long seedlings is inhibited, it is not conducive to the transformation of weak seedlings. The third is the high weed base, which is difficult to control in the spring. Some of the late-planted plots failed to be eliminated before the winter. The current high weed counts, coupled with the rapid development of weeding in the spring, will increase the difficulty of removing the plots. In addition, there are also threats such as waterlogging, late spring, etc. In view of the above problems, the current production of wheat oil should be based on the principle of “promote balance, attack large spikes, increase yields,†and focus on the “four preventions and one promotion†to firmly grasp the work of field management. The first is to prevent damage by waterlogging. Untrenched plots should be expanded to open trenches, shallow trenches should be deepened, and all trenches should be cleared quickly to keep them open and free from any waterlogging in the spring. The second is to increase the coverage of antifreeze damage. The lower temperature in the recent period will affect the normal growth and transformation of wheat oil crops. In particular, the plots planted in interplanting fields and banyan trees shall be planted in a timely manner by digging earth or applying mixed fertilizer to prevent freezing. Rape fields can be covered with straw to prevent freezing damage. The third is to eliminate grass and pests in a timely manner. If the average daily temperature is not less than 5°C, the field of "cold tail warmer" will not be removed until the winter has not been eliminated or eliminated. At the same time pay close attention to rape virus disease, aphids and wheat spider mites, sheath blight and other pests and diseases, timely prevention and control. The fourth is to take measures and prevent lodging. The wheat fields with large groups can be moderately repressed, and the ability to protect the locusts and freezing can be improved, or paclobutrazol can be sprayed before the jointing to control the plants and promote dwarfing and robustness of the plants. Prosperous rape fields can be controlled by cultivating loose soil and spraying paclobutrazol. The fifth is to promote transformation due to fertilization. Normally grown plots do not require fertilization. The emphasis must be on ensuring that the jointing, panicle, booting and rapeseed fertilizers are applied. Small, weak seedlings of the plots should be applied to transforming fertilizers, applying 10 kg of compound fertilizer or 5 kg of urea per acre. The drought-heavy plots should be combined with ditch irrigation and flooding, combined with the application of quick-effect fertilizer to promote the transformation of the seedlings.
