In view of the serious shortage of soil in the current situation, Heilongjiang Academy of Agricultural Sciences has organized experts to propose scientific and technical preparation for this year's food production. Experts have suggested that scientific and technological preparation should grasp important barriers such as drought-resistant water storage, variety selection, timely sowing, and residue of phytotoxicity. In the whole year of production, we must also grasp the prevention and control of pests and diseases, balanced fertilization, standardization operations, and scientific and technological training. An important gateway.
At present, the province's precipitation is scarce, and there is a possibility of forming a large area of ​​spring drought. In the drought-resistant water storage area, it is recommended that the spring sowing work be rushed to catch up early, and the dry land should be melted early, cleaned early, and pre-grounded to reduce water loss, so that it is timely and timely, to ensure 1 time. Sowing the seedlings to lay the foundation. For plots that do not have a deep foundation, it is necessary to grasp the slurry return period for topping and snoring, and with the smashing with the suppression; for the plots with deep foundations, try not to move the soil to prevent running.
Vigorously promote the technology of soybean ridges, no-tillage planting techniques, narrow-row cultivation techniques of soybeans, ridges after flat sowing, and inter-film mulching techniques of soybeans; corn in the arid areas of the central and western regions adopts the original ridges to sit on the water and gerrow the water. , filtering water sowing technology, the use of loose seeding technology in the low-wetlands in the east; rice cultivation in the greenhouse using the seedling raising technology; wheat should be mechanically snow-melted, top seeding technology.
Experts recommend that soil analysis be carried out prior to planting to develop a balanced fertilization program based on crop needs and soil fertility levels to ensure a bumper harvest. It is necessary to carry out reasonable deep application, layering application and staged application according to different soil quality and different conditions, and appropriately reduce the application amount of nitrogen fertilizer to prevent lodging late fall.
