1, ozone sterilization technology
(1) Pepper solar greenhouses are used to release ozone for 50 min to 60 min every night for a total of 3 months. No virus or gray mold is observed. The control effect of ozone on the virus disease and gray mold of pepper is 100%, the control effect on the disease is more than 90%, the pesticide cost is 24 yuan/0.5 mus in the experiment shed for 3 months, and the control shed is applied for 3 months. 8 pesticides to spend 184 yuan / 0.6 acres of pesticides, at least save the pesticide costs 160 yuan / shed, and the product is basically no pesticide residues.
Through statistics on the income from the actual sale of vegetables to the experimental shed and the two comparison sheds, which are 2,000 yuan and 1,400 yuan higher than the two comparison sheds respectively, it is estimated that the income of the vegetable shed for the quarter can reach more than 9,000 yuan, and the average saving cost of drugs is 160 yuan. / Shed, increase production and income is very obvious.
(2) The tomato solar greenhouse emits ozone for 40 minutes every day. After 3 days, the tomato's gray mold and leaf mold were treated. However, due to power outages and improper use of other machine functions, only air was released instead of ozone, causing tomato late blight. Difficult to come. In spite of this, in the experiment shed, except for the treatment of insect moths such as moths and moths, they did not fight drugs in the past two months, while the neighbors used sheds to fight drugs for 130 yuan in two months. Obviously, the use of ozone greatly reduces the amount of pesticides used to lay the foundation for the production of pollution-free vegetables.
(3) Cucumber greenhouse Due to more than 20 years of cultivation, soil pathogens increased, pesticide usage increased, cucumber yield decreased, quality declined, crop resistance decreased, and even “atypically lack of elemental disease†occurred. These diseases are serious. Restricted the economic income of vegetable farmers.
Farmers used the PZ-328011 ozone machine for cooking for only one month. The medication was significantly reduced, and ozone and pesticides were used to control the occurrence and development of cucumber downy mildew. At the same time, cucumbers were cured with ozone and sweet and sour liquid. The “Atypical Deficiency Syndrome†or “Difficulty†in greenhouses ———At first, there were only 5 pieces of green leaves per plant—6 green leaves. At the top of the plant, the entire shed was green and the photosynthesis intensity of the plant was increased. normal.
Through the trials and promotion, the maturity of the implementation of ozone sterilization technology has confirmed that the ozone sterilization is broad-spectrum and high-efficiency, cost-saving and efficiency-enhancing, and can reduce the dosage of pesticides by more than 50%. It is believed that through our continuous research, experimentation and promotion of this technology, this technology will create a new path for the development of the production of pollution-free vegetables and the development of high-efficiency agriculture.
2. Carbon dioxide application technology Xiaxian Agricultural Machinery Promotion Station has achieved significant production increase in Shangxinzhuang, Zhoucun, Jiecun, Shangbeishi and other villages respectively. From April 3rd to April 11th, 2004, Xie Cunfeng's cucumber shed at Fofeng was used to cast carbon dioxide for 8 consecutive days. Since the temperature rose, it can only be cast for 1 day per day. Each shed can increase production by 1O kg to 15 kg per day. The proportion of cucumber increased, and the average per bag increased by 1 kg compared with the greenhouse without adding carbon dioxide. That is, the test shed is 13 kg/bag and the comparison shed is 12 kg/bag. If in the winter or early spring, the effect will be more pronounced, and the price will be better. With the addition of carbon dioxide gas fertilizer, it is also evident that the leaves become thicker and wider, the color becomes dark green, the root system is developed, the fruit setting rate is increased by more than 60%, and the morning city is 8 days to 10 days, delicious taste, high nutritional value, and increased yield More than 20%.

According to the number of barrels, Piston-typed Mobile Milking Machine can be divided into two categories: Single-barrel Type and Double barrel Type.
With unique design, easy operation, easy maintenance, it can lower the utility costs. It will not hurt the nipple by milking soft with stable vacuum. The milking cup group is with a transparent tube, so the operator can observe the nipples of cows during the milking.
After years of production and constant technological improvements, the new designed milking machines can meet the actual demand for the majority of users. We discuss and improve more about the machine, to make them catch international standards, and suitable for more users in different countries. The portable Milking Machine is not only used for the individual animal in small farm, but also provides a selection for large-scale dairy farms for some special animals.
