To strive for proper sowing and scientific determination of the best seeding period for the semi-winter cultivars in the Huaibei region in mid-October, the semi-winter spring cultivars along the Huaihe River in late October, and the spring cultivars in the Central Jiangsu Province in late October. At the beginning of November, the spring varieties in southern Jiangsu were from the end of October to the beginning of November. Appropriate early sowing using precision sowing, the basic seedlings per acre control within 120,000; appropriate sowing semi-precision seeding, basic seedling control at 160,000 or so. To miss the appropriate sowing date, appropriate increase in the amount of sowing, nightly sowing 1 day per acre increased 0.5 million to 10,000 basic seedlings, up to 80% of the expected number of spikes (cultivated in late sowing stalks, Huaibei area up to no more than one acre 350,000 basic seedlings, no more than 250,000 basic seedlings per mu in the Huainan region. When the seed germination rate is normal and the sowing time is appropriate, the sowing amount can be determined according to the principle of "kind of tens of thousands of seedlings." The seedling emergence rate in the field under low sowing temperature is only about 70%. The appropriate seeding rate should be determined according to factors such as seed germination rate, 1000-grain weight and field emergence rate.
To avoid poor cultivation and poor planting, increase the uniformity of sowing wheat in our province is dominated by rice bran, rice plentiful in most areas is late, rice paddy soil is poor in suitable tillage, and the suitable tillage period is short. This requires that according to conditions such as cornices, soil, lyrics, and climate, local conditions should be adopted to appropriate sowing methods, to grasp the progress of sowing, to avoid cultivating rotten species, to ensure that all seedlings sowing, to achieve seedlings, seedlings, strong seedlings. Earlier rice harvest, timely cultivating (recovery of rice to the appropriate time of 5 to 7 days), soil sand to loam, suitable moisture conditions, the soil is suitable for the state of tillage, can take free (small) cultivator drill; harvest rice Immediately after sowing, the soil moisture is too high, and the seedlings can easily cause the lack of seedlings and ridges. It is advisable to use man-made plates with shallow rotation and artificial or mechanical even spreading; The relative water content of the soil is in a saturated state, and the soil is heavy and poor in ploughability. Tillage machinery operations often result in cultivating and cultivating crops. They can only be planted directly on rice stalks without tillage, and Taihu Lake is also called “press platen wheatâ€. Tengyu is later than the time that the wheat can be planted at the appropriate time. The rice cultivars can be planted in paddy fields and planted 7 to 10 days before the rice is cut to ensure proper early sowing of the wheat. Both the old rice and the early wheat are correct.
Scientifically Deploying Fertilizer, Applying Basal Fertilizers High-efficiency fertilization of wheat should follow the principle of “giving full use of basal fertilizer and recharging planting and extending panicle-fertilizerâ€. The level of fertilization differs due to differences in soil fertility. Generally, the pure nitrogen amount per hectare over 500 kilograms per mu should reach 15 to 20 kilograms, and the ratio of pure nitrogen, phosphorus pentoxide, and potassium oxide should be about 1:0.6:0.6. According to the requirements of quality-tuning cultivation techniques, the nitrogen fertilizer management method for weak gluten wheat is 7:1:2 for base fertilizer, balance fertilizer and jointing fertilizer, and the base recovery ratio of nitrogen fertilizer for strong gluten wheat is controlled at about 5:5. The nitrogen base fertilizer and top dressing of medium-gluten wheat are applied. The ratio is about 6:4. Phosphorus and potassium fertilizers are based on the combination of the basic recovery, the general base recovery ratio of 5:5.
Supporting ditch system, it is an important guarantee for the high yield of wheat in the Huainan region. To vigorously promote the machine to open the ditch, to ensure that the inner third and the outer ditch matching, so that a wheat field, two water, supporting the three ditch, four empty, rain only dry, can irrigation can row, drought and flood protection. In the Huaibei wheat area, we must gradually promote the northward shifting of the southern ditch, overcoming the idea of ​​re-irrigation and light drainage, and strive to reach the ditch system standard for the Huainan wheat field. The drought and buckwheat vigorously promote the deep ditch sorghum, which can both save water and reduce flooding. . To achieve a kind of management, we must timely fill gaps, cover seeds, make up for cracks, make up for Miao Fei, etc., and strengthen field management.
