1, gibberellin. When the eggplant is in flowering, spraying the leaves with 10-50 mg/L gibberellin can promote fruit setting and increase the yield; in the flowering period of the eggplant, spraying with 10-50 mg/L Gibberellin can promote fruit setting. Prevent empty fruit. 2, 5406 cytokinin. 30 days after planting, eggplant is sprayed with 600 times liquid, sprayed 1f times every 10 days, and sprayed 3 times in total, which can preserve flowers, protect fruits and early maturity, and increase production by about 30%; tomatoes use 400-450 from 4 leaves. Double liquid spray, spray once every 10 days, spray 5 times in total, can keep flowers, preserve fruits, increase production by more than 25%, can also reduce leaf mold and mosaic disease; potatoes with their 100 times liquid before soaking potatoes Block 12 hours, during the growth period with its 600 times continuous spraying 3 times, can increase production by more than 25%. 3, increase production spirit. During the budding and flowering stages of tomato, spraying with 20-30 mg/l yield-promoting spirit can prevent flowering and fruit drop. 4, anti-dropping factor. In the tomato flowering period with 20-30 mg / l anti-decorin planted or sprayed, with obvious fruit protection and increased yield, especially in the first 3 - 5 flower inflorescence application, the most obvious increase in production; eggplant flowering time with 20-30 mg / The anti-dropping spray can prevent flowering and increase the early yield; the initial flowering period of pepper is sprayed with 20-30 mg/L anti-dropping agent to protect the fruit and increase the yield. 5, 2, 4 - D. Tomato tomato flowering with 2,4 - D 20-30 mg / l silk flower or spray can increase the fruit set rate of tomatoes; eggplant flowering with 2,4-D25-50 mg / l spray or flower can increase production. 6, naphthalene acetic acid. At the turn of the spring and summer, when the tomato is easy to fall in the low temperature or high temperature season, 10-25 mg/L Naphthylacetic acid can be sprayed to prevent flower drop, re-spray or spray on the growing point; during the flowering period of pepper, 50 mg/L Naphthylacetic acid can be sprayed Effectively increase the yield of peppers; methyl naphthylacetate is sprayed on dried soil and paper scraps to make up medicine soil, and then mixed with potatoes. One kilogram of potatoes uses 200-300 milligrams, which can inhibit the sprouting of potato chips during storage. 7, ethephon. In order to make the tomatoes available in the morning market, when the tomato fruit has grown, the yellow can be sprayed with 1000-2000 mg/liter ethephon or smeared with the tomato fruit, so that the fruit can be matured earlier, and the green tomato can also be taken off. - Immerse the 1000 mg/L liquid for about 1 minute, remove it and place it at 20-25°C. It also has a ripening effect. 8, than long. When the tomato 1 leaf and 4 leaves were sprayed with 2500 mg/litre each time, the vegetative growth of tomato was inhibited and the fruit set was promoted; at the initial stage of potato flowering, 3000 mg/litre was sprayed on the plants for 1 time to suppress stems. Excessive, increase tuber growth. 9, Qingsu element. 14 to 21 days before potato harvest, 2000-3000 mg/L of Qingxin was sprayed on dry soil and paper scraps to make up the soil. Mixing it with potatoes inhibited potato shoots from sprouting during storage. 10, sodium nitrate. Can be soaked with sodium nitrite 6000 times liquid tuber potato tuber 5-12 hours, cut open sowing; in the tomato growing period and bud stage with sodium nitrite 6000 times sprayed 1-2 times, conducive to plant growth. 11, Chlormequat and Chuang Shuang. In the 3-4 leaf stage of tomato seedlings, spraying tomatoes with 500-600 mg/l of Chlormequat can cultivate dwarfing and strong seedlings and increase the seedling-suspending rate of transplanting; and can use 0.3% of Chlormequat for seed coating. To cultivate tomato strong seedlings and increase the stress resistance have a certain role; in tomato breeding period, after planting and early flowering period, all plants can be sprayed with 100-150 mg/L of CHZ, so that the plants can be moderately dwarfed and rooted. Promote early flowering results and improve cold resistance.
