Total wheat straw returning measures

There are nearly 800,000 mu of rice-wheat wheat in Donghai County. In recent years, some problems have been exposed during the practice of returning the entire amount of rice straw to the field. That is, straw-resistance wheat is vulnerable to cold, drought, and rot resistance, affecting yield. Further improvement was mainly due to the unreasonable method of straw treatment and the lack of adequate grass remediation measures, as well as the lack of a suitable cultivation technique for wheat with straw in full. By changing the method of returning to grass, improving the quality of ploughing, adjusting fertilizers and water, and strengthening post-planting management, it is possible to solve the above-mentioned problems well and make it possible to fertilize fertility and achieve high and stable yields of wheat.
Harvest the good rice by using a harvester with comminuted grass and even grassing equipment. Keep the rake at a height of 15 cm or less, smash the grass to a length of 5 cm or less, and spread it evenly. Turn and bend the head of the harvester and turn it around. For reasons such as the formation of uneven grass, artificial grass should be collected after harvest.
The return of soil moisture to soil quality has a great influence on the quality of grasses. In general, the dry soil is conducive to returning the grass to the fields. Under conditions of high humidity in the field and soil erosion, not only the quality of machinery is returned to the field but also the operation is difficult and the fuel consumption is high. . To do a good job in the later stage of rice water slurry management, timely water cut, generally sandy soil in the 10 days before harvest water cut, clay land cut off 15 days before harvest, so that the relative soil moisture content maintained at 60% to 85%.
Improve the quality of returning grass by using 2 rotary tillage operations. Use powerful tractors with counter-rotating cultivators to increase tillage and burial depth, so that the stalks are distributed evenly on the tillage layer. When farming, anti-rotation rakes should be placed on high grades, and the tractors should be placed in slow stalls. Rotation tillage depth of 18 to 20 centimeters, appropriate repression after rotary tillage, sinking the soil, to achieve virtual reality, flat surface.
Improve the quality of sowing and grass after using the no-till cultivator shallow rotary tilling or sowing, drill seeding machine is best to use disc-type legs, can avoid blocking the eyes and cause seedling off ridge, so that the same depth of seeding (2 to 3 cm ), falling seeds evenly. Use a conventional planter with a kick to kick the soil, so as not to obstruct the stalks and open the soil by throwing soil on the front rotary cultivator. The soil thickness is about 2 cm.
After the suppression of sowing, the repression of the repressors used in the conventional conventional planters is insufficient, so they must be repressed after sowing, and they can be mechanically repressed or artificially repressed. When the soil moisture is suitable or dry, the soil is immediately repressed. When the soil is rotten, it should be repressed after the top soil is slightly dry.
Improve the quality of open-ditch straw to return wheat requires appropriate shallow sowing, but shallow seeding is inevitable after emergence. To improve the quality of trenching, increase the density of open trenches, and cover the dew-proof seeds with trenches.
Nitrogen-enhancement straws need to absorb a certain amount of nitrogen from the soil during the early rot, and the amount of nitrogen fertilizer should be increased when the straw is returned to the field.
For the plots that are insufficiently planted with sufficient moisture, the Qimiao water should be poured after sowing, so as to prevent the root system from being overturned or unable to leave the seedlings after emergence.
Appropriate increase in sowing volume Although a series of measures have been adopted to improve the quality of returned crops, there are still a large number of straws remaining in the tillage layer. The quality of the sown and sowed seeds is still worse than that of the straw-free ones. The emergence rate is relatively low, and the seeding amount per acre is increased by 2.5 kg. About to ensure enough basic seedlings. The suitable sowing date for local rice and barley wheat is from October 10 to 25, with 120,000 basic seedlings per acre planted within the appropriate period, and 160,000 to 200,000 seedlings per acre planted at an appropriate date. Basic seedlings per acre of 210,000 to 250,000, later than the minimum suitable broadcast sowing every night 1 day per acre to increase the basic seedlings 0.5 million, the maximum no more than 350,000 per acre.
Timely pouring of frozen water and returning green water to straw decomposition requires a lot of water. When the soil moisture is insufficient, not only the decomposition of the straw is affected, but also it competes with wheat for water. Before and after “Big Snowâ€, it is necessary to seal the frozen water in time and pour it back to Qingshui early in the year to meet the water needed for the growth and development of the wheat seedlings.
