Kang Zhuangsu's field trial

Our company started to promote the use of Kang Zhuangsu in early 2006. At that time, Zhang Yong, a villager from Xihui Village, Hongqiao Town, Yutian County, was looking for his sweet pepper field as a test field. The first time I used Kang Zhuangsu was on April 20th. Before the sweet pepper was transplanted, Zhang Yong sprayed Kang Zunsu on some of the relatively small and weak sweet peppers for the more obvious test results. It was transplanted to the ground on May 1 and no obvious changes were observed. A few days later, the change began to manifest itself. First, the survival rate of the seedlings sprayed with Kang Zhuangsu was high, and the slow seedling period was short. In addition, the sweet peppers sprayed with Kang Zhuangsu began to express his resistance to disease. On May 20th, the second time Kangyansu was sprayed, the effect became more and more obvious. The test field was given twice on average (Kang Zhuangsu), and a green bolly foliar fertilizer was sprayed during the flowering and fruiting period, and an insecticide was once applied. At the time, the control field used the head saplings, sprayed the fungicide and antiviral agent five times, the insecticide twice, and the green bolly foliar fertilizer once. The weather was not good these two days, and the control field began to get sick again, and the test field sprayed twice by Kang Zun was safe and sound. In terms of the fruit-hanging rate, the fruit-bearing rate of the test field averaged 10-12 fruits per plant, the flower shape was strong, the fruit was uniform and thick, and the fruit-cutting rate of the control field was 6-7, which was obviously thin. The sweet peppers in the test field are strong, the stems are thick, the leaves are thick, and the medium leaves are 1-1.5 cm larger than the large leaves of the control field. There are many flowers. For the current cost, the cost of the test field is 40. The yuan is around, and the control field is currently over 100 yuan. According to the expected output, the yield per mu will be more than doubled. Our test house is very savvy. She took a few generations of Kang Zun in his control field today because he can't stand such a large difference in production and pesticide input. I am very grateful to him for giving us products. Incomparable trust and great support.
