Li Junjun: Why does my pepper harvest every year?

"I plant Chinese prickly ash, but very few people die of illness. There is a Chinese prickly ash tree in Shiwan Zanthoxylum bungeanum Garden. It is more than ten years old, 30 centimeters thick, and its crown covers an area of one centimeter. It can pick 300 jin of fresh pepper a year. I have planted more than 1000 prickly ash now. In 2015, I harvested 1500 kilograms of dried pepper, with an income of more than 70,000 yuan. This year, I can harvest 2000 kilograms of dried pepper, with an income of more than 100,000 yuan. "

Li Junjun is a big Chinese prickly ash grower in Lijiawan Village, Longfeng Township, Wudu District, Longnan City. he grows Chinese pepper with less disease. Li Junjun has his own set of techniques in the prevention and control of pepper diseases and insect pests. "the bactericidal mechanism of stone-sulfur mixture in winter is that it can produce ionization in aqueous solution, and its hydrophilic group contains strong positive charge, which absorbs all kinds of bacteria and viruses which are usually negatively charged, thus inhibiting the reproduction of bacteria and viruses, solidifying bacterial proteins, denaturing bacterial enzyme systems, and the film formed by polymers blocking the ion channels of these microorganisms. Make it immediately suffocate to death, so as to achieve the best germicidal effect. In order to increase the germicidal efficacy, some dichlorvos can be added. "

From January to March, the larvae in the Zanthoxylum bungeanum garden are about to break their eggs, so they can smear the tree trunk and spray medicine once. From June to September, the pests are in disorder and begin to breed. At this time, Hou smears the medicine once, which is very effective.

In recent years, the prevention and control of diseases and insect pests of Zanthoxylum bungeanum in Wudu District of Longnan City has become more difficult. Many prickly ash died of rhizobium, root rot and longicorn beetle pests as soon as they entered the full fruit stage. Li Junjun's exploration in terms of medicine and timing is worth popularizing.
