Today, 17 january, journalists learned from the agricultural rural department of zhang zhang zhang zhang district of the city of zambo that, in order to increase the city's capacity to respond to extreme winter weather emergencies, to establish a better system of preparedness and response, to minimize damage to disasters and to ensure safe production, the agricultural rural department of zambo has developed technical guidelines for the safe production of extreme weather fruit trees in zambo city。
According to the opinion, the facilities plant fruit trees, with particular attention to cold-resistant work, the tight sealing of the film when shackling, the prevention of wind breakage, the filling of hot materials such as cotton and grass curtains at night, and, if necessary, the construction of sheds within the sheds to form a double layer of temperature protection。
At the same time, close attention should be paid to the weather and appropriate tree-plant emergency protection should be prepared. Early in november, the strawberries shack began to detonate the temperature, usually at less than 5 °c, then went to hibernation, and at less than 0 °c, frost, so the night temperature could not normally be less than 7 °c. Grapes, large cherries, etc. Generally reach their cooling levels in mid-january, when they begin to keep the shed warm, and when they are released from hibernation, the temperature in the shed should be above 0°c to prevent freezing。
(c) timely monitoring of weather conditions, reinforcement of sheds, such as snow in the event of heavy snowfall, timely removal of snow from the balconies after snowfall, failure to heat during the day, continuous coverage of temperature-conservation features and setting up of heating facilities, such as heating blocks, in the shed。
Strengthening tree management in the shed. Improved management of fertilizers, higher water requirements for strawberries and frequent humidity of soil, coupled with timely pursuit of compound or leaf-based fertilizers during the extended period of current curvature and gravitation. Strengthened plant management, timely removal of leaves and runners, and extra armpit sprouts. The grapes are sprouted in time for the management of the fields such as chicken binding, sprouts and sprouts to ensure that the trees are strong. The pre-chrysanthemum fruit is picked up several times with a view to fertilizing the leaves and ensuring that the soil contains approximately 60 per cent water。
Timely prevention and control of pests and diseases. Strawberry diseases are asymptomatic, dusty, anthrax, and so on. Grapes are mainly frosty, as well as as corrosive, fibrosis and so forth. The green anti-control requirement for the safe production of fruit quality requires timely preventive measures to be taken to ensure quality of fruit by matching the foliage with the application of a specific substance。
The opinion requires that the open-air fruit tree pay close attention to weather forecasting to prevent losses from falling into the cold. When fruit trees start to move, especially during fresh hairs and sit-ins, the weather forecast is followed closely and the late spring frost prevention is initiated when temperatures are forecast to be below 2°c。
Timely water before cooling can improve soil conditions, reduce temperature variability on the ground and protect against early spring frost. The temperature of the tree body after water is observed to be 1 °c ~ 2 °c at night compared to that of non-water。
On the night of the frostfall, it usually occurs between 12:00 p. M. And 0800 p. M., when the whole garden canopy is sprayed with fog or 0. 5 per cent of sugar cane. The water is frozen into condensed ice and released into the submersible heat, which increases the temperature and mitigates the frost hazard。
The fumigation can only be applied in the event of radiation frost (at not less than 2°c) and the effect is only about 1°c, which is less effective if the temperature is less than 5°c. There are two types of smoker: frost-resistant aerosols, with a formulation of 20-30 per cent ammonium nitrate, 50-60 per cent sawnock, 10 per cent spent diesel and 10 per cent fine coal powder. 2 is a common smoker whose raw materials are seed straws, weeds, leaves, etc. The temperature is activated as soon as it is down to -2°c. Three to four piles per acre of orchards. If the pile is too hot, it can crush the soil and smoke it。
Spraying of hormone-like substances such as ethrin and heaven 2116 before the frost increases the resistance of fruit trees to thaws by corrosive fats such as potassium phosphate, calcium aminoate and boar sand。
Before the freezing, the fig tree anti-frozen agent + pbo is 50-100 times more liquid, and the anti-frozen effect is good. Home-made anti-freeze formulations: 8 per cent of gum, 3 per cent of glycerine, 43 per cent of glucose, 45 per cent of sugar cane, 2 per cent of other nutrients (fertilizers, hormones, etc.) and 5,000 to 10,000 of clean water。
Strengthening of the management of flowers and artificial pollination; application of boron and associated plant growth regulation agents to promote sit-ins; strengthening of the management of fatty water and the pursuit of complex fertilizers such as fruit tree-specific fertilizers, in particular the preparation of foliage fats for the foliage of pixie biostimulants + tasil esters to mitigate or spray nutrients such as 0. 3 per cent of potassium phosphate or 0. 3 to 0. 5 per cent of urea, 7 to 10 days in length, until the end of june; rational retraction, without rushing or removal of the affected branches, leaves or fruit in the short term, and late-sicking and extra fruit; and the opening of horns for trees to control nutritional growth。
