From October 3 to 6, 2021, during the National Day holiday, Wang Shangkun, the science and technology commissioner of Henan Province, took the special whitening agent purchased for the majority of fruit tree growers to Tianzhuang Village in Baji Township, Yancheng County, and the Agricultural Science Research Institute of Yancheng County to carry out scientific and technological services for the autumn cultivation and management of fruit trees.
Rooted in the grassroots, bowed to the wilderness
At the office of the Tianzhuang Village Committee, Commissioner Wang Shangkun and Ding Shouxiang, director of the village committee, exchanged views on the content and specific arrangements of the scientific and technological services. First of all, Commissioner Wang Shangkun gave a specific training and explanation to the farmers who planted peach trees in Tianzhuang Village on the content of autumn cultivation management in the village committee. Commissioner Wang Shangkun pointed out that the main content of the current autumn cultivation management of peach trees has six points: First, deep ploughing and application of base fertilizer. From late September to early October, 1 meter from the trunk, combined with deep turning 30-40 cm, fully decomposed farmhouse fertilizer 4000-5000 kg / mu, calcium superphosphate 150 kg / mu. According to the nutritional status of the tree, add an appropriate amount of urea 10-15 kg / mu, ferrous sulfate 2-3 kg / mu. In case of drought, irrigate once. The second is pest control. Foliar spray with 26% chlorpyrifolide wettable powder 1500-2000 times liquid to control a little leafhopper and bugs, 25% urea suspension emulsion 2000 times liquid control peach leafminer moth. Ropes or grass handles are tied to the main trunk and branches to trap pests, and they are removed in late autumn or early spring and burned. The third is foliar spray fertilizer. Spraying 0.3%-0.4% urea after fruit harvesting improves leaf photosynthetic function and prolongs leaf life. The fourth is autumn pruning. It is mainly for the heart or shear of new shoots that have not stopped growing; for those that do not control the removal of the branches from the base. The newly grown second and third branches are removed from the base. The branches with small angles of the backbone branches pull the branches open the corners. To pull the branches, you must first take the branches, and then pull the branches. Grasp the "base does not bend the bow, the tip does not sag", to avoid pulling into a bow shape. Pay attention to the drop head, control the height of the tree, and control the height of the tree at 80% of the line spacing. Fifth, frozen water. Rinse frozen water once before freezing to maintain the supply of overwintering water. Sixth, the trunk is painted white. The special whitening agent of Beijing Linhai Plant Protection Technology Co., Ltd. was prepared according to the instructions to whiten the trunk and branches of the peach tree. After the training, Commissioner Wang Shangkun interacted with the growers and answered their questions. The atmosphere of the training site was lively and was warmly welcomed by the majority of fruit farmers.
After training the technology, Commissioner Wang Shangkun and Ding Shouxiang, director of the village committee, distributed a special whitening agent for fruit trees for peach tree growers. Everyone said that after going back, they will conscientiously do a good job in the autumn cultivation and management of peach trees in accordance with the technical requirements of the commissioner's training, so as to obtain greater benefits in the coming year.
Subsequently, commissioner Wang Shangkun came to the home of peach tree grower Zhang Xuezhong to provide targeted technical guidance on the peach trees he planted. In view of the actual situation of the orchard, commissioner Wang Shangkun put forward the current management suggestions: First, in accordance with the technical requirements of training, we should pay close attention to doing a good job in autumn shearing. The second is to carry out deep base fertilizer between peach tree rows in time. The third is to protect leaves and raise roots and strengthen trees. Fourth, the tree body is painted white. In this regard, Zhang Xuezhong's lover said that we must conscientiously do a good job in the current 4 tasks, and complete them with quality and quantity.
Connect with farmers and benefit the villagers
At the Institute of Agricultural Sciences of Yancheng County, commissioner Wang Shangkun, through exchanges and communication with Director Zhou Zhe, put forward a management consensus on the grapes cultivated in the current demonstration base: First, apply the base fertilizer in autumn. The application amount is 100 kg/plant according to farm manure, and a small amount of potassium sulfate phosphate is mixed. The fertilization method is ditch application: 30-60 cm from the root neck, east to west or north and south sides, dig a ditch 50 cm deep and 30 cm wide, apply fertilizer, mix well with the soil and cover the soil, and change the position every year. The second is autumn shears. It is mainly to thin the secondary branches, tie the branches, pick the hearts, pick the old leaves, and the diseased leaves. Thinning the secondary branches is to remove some of the dense secondary branches. The tying is the timely binding of the branches that need to be tied. Heartbreaking is a strict heartbreak that continues to retain the secondary tip. Picking old leaves and diseased leaves are medium and late ripening varieties that need direct light to color, and when the fruit begins to color, the old leaves that are close to the ear of the fruit are removed so that the ear can see the direct light. The third is to pay attention to the prevention and control of diseases. In autumn, grape diseases and insect pests are mainly downy mildew, brown spot disease, powdery mildew and so on. 1:1:(200-240) Bordeaux liquid can be sprayed for control. When downy mildew is severe, spray 80% acephosphine aluminum emulsion 600 times liquid + 50% cream urea cyanide emulsion 1500 times liquid; in severe cases of brown spot disease, spray 800 times the wettable powder of 80% daisen manganese zinc + 10% polyoxymycin 1500-2000 times liquid. The management consensus formed for the cultivation of pear trees in the demonstration base is: First, the application of basal fertilizer in autumn. Organic fertilizer and fast-acting fertilizer marriage. Apply organic fertilizer 3000-5000 kg /mu, urea 20-30 kg/mu, calcium superphosphate 30-50 kg/mu, or fruit tree special fertilizer 150 kg/mu, timely watering after application, fertilizer source is insufficient when the pressure straw, leaves, weeds, etc. It is alternately performed by digging a ditch between the rows of pear trees or digging a hole. Fertilization depth 30-50 cm. Timely irrigation in times of drought. The second is autumn shears. Grow too strong trees, and properly remove a small number of new shoots and long branches. Perennial branches with small opening angles pull branches and open horns. Moderate and weak trees do not thin branches. Three shi deep ploughing garden soil. Between the rows of fruit trees 50-80 cm from the trunk turn 30-40 cm deep. Fourth, control of diseases and insect pests. Remove dead branches and leaves, zombie fruits, rotten fruits and weeds around the orchard in time, and concentrate on fertilizer or burn. For pear black star disease and black spot disease, alternating sprays such as Dasheng M-45, carbendazim and Bordeaux liquid were used for control. Red spiders are controlled by avermectin and gmeth, and mesophores are controlled by ethyl spirostilben. Fifth, the trunk is whitewashed. Subsequently, Commissioner Wang Shangkun presented 4 bags of fruit tree special whitening agent produced by Beijing Linhai Plant Protection Technology Co., Ltd. to Director Zhou Zhe, for which Director Zhou Zhe expressed his deep gratitude on behalf of the institute.
Unconsciously, the 4-day technology service has come to a successful end. Commissioner Wang Shangkun fulfilled his duties and missions with his own practical actions and made his due contribution to the rural revitalization strategy currently being implemented. ③5
