1. SA-1 water absorbing agent seed dressing. The SA-1 water absorbing agent is a super absorbent resin, which can greatly improve the water absorption rate and water retention of the soil, and has a good fertilizer-preserving effect. According to the test, the SA-1 water-absorbing agent with 1.5 to 2% of corn seed was seeded, and the plot was planted in a field with a water content of only 8%. The emergence rate was 85-90%, which was 10-15% higher than that of the control group.
2. Administration of aspirin. The chemical name of aspirin is "acetylsalicylic acid", which can be decomposed into salicylic acid and acetic acid in water. After entering the plant body, it can reduce water transpiration and thus resist drought. The test showed that before sowing, soaking with 0.05% aqueous solution of aspirin for 12 hours can increase the emergence rate by 15-20%, and the seedlings grow stronger and increase the yield by 6.5-8%. When the corn grows in the drought, the leaves are sprayed 0.05~ 0.1% aqueous solution of aspirin can significantly reduce the drought, with an average yield increase of more than 10%.
3. Cover the wheat straw. According to the test, after the jointing of the corn (in the middle and late July), every 667 square meters covered with 200-300 kilograms of mashed wheat straw in the field soil surface can not only increase rainfall infiltration, but also improve water storage capacity. It also inhibits weed growth. Break the soil compaction. Advantages such as fertility and fertility can increase production by 7 to 16%.
4. Spray a drought-resistant agent. The chemical component of the drought-tolerant is fulvic acid. The main function is to reduce the transpiration intensity of the leaves, improve the vitality of the roots and prevent premature aging. In the case of drought, the drought-resistant agent No. 1, FA dryland dragon or biochemical fulvic acid 80-100 grams per 667 square meters, spraying 50-75 kilograms of water, the yield increased by 9 to 17.2%.
