Vegetable growers Lao Xu's annual vegetable production is very high. Is there any special technology? The people in the village are envious of him, and some people are vomiting. Why do you have so much difference between the output of the village and the old Xu family? The same land, the same fertilizer, the same management method, why is the gap? Did he steal any hands and feet? It’s too mad. The reason why the old Xu family's output is high is because the old Xu grafting technology is high. What are the benefits of grafting? Do you really know the growers? Enhance crop disease resistance For example, farmers like to graft cucumber with glutinous pumpkin, which can effectively control cucumber wilt and delay the occurrence of downy mildew. All kinds of eggplants have known that once eggplant verticillium occurs, it will cause the eggplant to die. Farmers can use tomato as a rootstock to graft eggplant, which can effectively prevent and control. Improve crop cold tolerance Because the rootstock is more robust and developed, and the stress resistance is good, the grafted seedlings are more resistant to low temperatures. Black squash pumpkin grafted cucumber, cucumber in the ground temperature of 12 degrees Celsius, the temperature of 6-10 degrees Celsius, cucumber roots can still grow normally. Overcome the danger of continuous cropping The root system of cucumber is relatively fragile. Once it is continuously cropped, it will be affected by salt accumulation and harmful substances in the soil. After farmers use black squash to graft, they can greatly reduce the harm of heavy mites. Increased crop root absorption capacity After grafting, the roots of plants increased exponentially compared with self-rooted seedlings, and generally absorbed 30% more nitrogen and potassium than self-rooted seedlings. 80% phosphorus. And the deep phosphorus in the soil can be effectively utilized. Increase crop yield Grafted seedlings have large stems and can increase yield by more than 40%. For example, farmers use tomato late-maturing varieties as rootstocks, and early-maturing varieties to make scions, which not only can make tomatoes premature, but also shorten the fruiting period and greatly increase tomato yield. Have you learned from vegetable growers? If you want high-yield vegetables, you have to accumulate experience in the usual planting and try more planting methods and techniques. For more details, please pay attention to Hui Nong. The school has new agricultural technology knowledge to share with everyone every day!
