First, sour vinegar sprayed on vegetables, fruit trees, can improve the utilization of light energy, increase production and improve quality. Vegetables especially like to eat "acid." Solanaceous vegetables start from 1 to 2 days after colonization, spraying once every 7-10 days, and spraying 3 to 5 times 300 times vinegar solution, which has better control effect on tomato and pepper virus diseases. , Tomato can increase production of 10-34%, pepper, eggplant can increase production by more than 8%. Before cucumbers bloom and bear fruit, 0.5 kg of vinegar per acre and 50 kg of water are sprayed, which can increase production by 18-20%. In the five leaves of Chinese cabbage, with 200 times vinegar solution, spray once a week, even spray four times, can increase production by more than 10%, and can effectively prevent soft rot. Spray spinach, water spinach, watermelon, squash, and potatoes with this method. From the seedling stage, spraying once every 5 days, and even spraying 2-3 times of vinegar for 2-3 times, the effect of increasing production is very obvious. Fruit trees also like to eat "acid." In the young fruit period, fruit expansion period, fruit coloring period and fruit harvesting period 15 days after fruiting, spraying 250-500 times vinegar aqueous solution, respectively, can increase production by 10-30%, and can improve the storage capacity. Although fruits and vegetables love to eat "acid", but can not replace the use of other fertilizers, it should be noted that vinegar can not be mixed with alkaline grass ash, washing powder, pesticides mixed spray, so as to avoid acid and alkali neutralization and failure. And dosage and spraying time, number of times must be mastered. Second, a sweet candy. Sugar can be used as a foliar fertilizer on vegetables and it can also be used to control some diseases. Spraying 0.2% sugar in the cucumber seedling stage can make the seedling thick and enhance the plant's resistance to downy mildew. Sprayed once during the melon period, the melon strips have a particularly good taste. Spraying cucumber with 1% sugar solution can also prevent viral diseases. Spraying 0.75% of sugar liquid and 0.2-0.3% of urea mixed liquid as foliar fertilizer during tomato fruit setting can make flower bud hypertrophy and flower head thick. During the flowering season, if the leaves are shriveled due to the high concentration of hormones, spraying 2-3 times of 0.5-0.7% sugar can make it as soon as possible. The timely application of 0.2-0.5% sugar solution during frost damage can significantly reduce the incidence of tomato disease. In the watermelon enlargement period, spray the leaves 2-3 times or 2-3 times with 300 times diluted sugar solution to increase the sweetness of the watermelon. 2 milk. When the strawberry is inflated and whitened, milk is added to the water for drip irrigation. Each time the dosage is 25-30 kg per mu, it is appropriate to use 3 times throughout the growth period. After the first milk chase, the temperature of the shed should be controlled 2-3 degrees higher than the normal temperature. After 3 days of using milk, it works. No need to chase chemical fertilizers. The strawberries are big, sweet, and have high yields.
