Build a greenhouse and raise the water level to deal with busy planting and breeding

Original title: to build a greenhouse and raise the water level, growers and farmers are a little busy.

While we are enjoying the frozen beauty of the West Lake, green vegetables, Chinese cabbage and strawberries are resistant to cold and cold.

For growers and farmers, snow and "quick freezing" after snow is really a double hurdle. Yesterday afternoon, the reporter learned from the Hangzhou Bureau of Agriculture that at present, Hangzhou's major fruit and vegetable planting bases and aquaculture bases have taken anti-freezing and heat preservation measures. As the temperature is still relatively low today and tomorrow, anti-freezing and heat preservation is also the main work of farmers and growers in the next few days.

Zheng Junhui, deputy director of the farming Department of the Municipal Agricultural Bureau, said that relevant protection notices have been issued to 425 "vegetable basket" bases in Hangzhou, and the basic anti-freezing measures for each base have been put in place. Judging from the current situation, there is no problem with the normal supply of vegetables, but the temperature is still relatively low today and tomorrow, and the anti-freezing of vegetables is still not allowed to be slack.

"vegetables such as Chinese cabbage and Chinese cabbage are freeze-resistant varieties, but they can only tolerate low temperatures ranging from minus 1 ℃ to minus 2 ℃. If the temperature drops to about 10 ℃ below zero, it will also have a great impact on these leafy vegetables, and the anti-freezing situation is still quite severe." Zheng Junhui said.

Wang Guohai of Hangzhou Agricultural Bureau said that loquat and strawberries had a great impact on fruit cultivation in our city. "the planting area of strawberries in our city is about 20,000 mu, which is currently in the peak season. Strawberries belong to berry fruits, which are easy to freeze at low temperature and their growth will be slow. Growers should reinforce and insulate the planting greenhouse and, if necessary, build an arch shed in the greenhouse for thermal insulation. " Wang Guohai said, "the young fruit growth of loquat will also be affected, it is easy to freeze at low temperature, and the yield this year will be damaged to a certain extent." In addition, the leaves of citrus fruit trees will be frozen off when they are exposed to low temperature, which will also affect the fruit. We have organized professionals to provide relevant anti-freezing guidance to growers. For fruit growers, anti-freezing work can not be ignored. "

Wu Xiaolan, deputy director of the Fisheries Department of the Hangzhou Agriculture Bureau, said that as the breeding cycle of most farmed species has ended, the cold wave does not have a great impact on aquatic products. However, for aquaculture in outer ponds, farmers need to improve some overwintering facilities, such as raising the water level and building greenhouses. In addition, for outer pond culture, many conventional fish species need to strengthen culture management to prevent frostbite.

Link: a few days ago, the Department of Agriculture of Zhejiang Province and the Bureau of Agriculture of Hangzhou released current measures for major crops and fisheries to deal with cold waves, rain and snow, which can be used as a reference for growers and farmers:

1. Vegetables

1. Rush to harvest vegetables in advance to avoid frost injury and snow pressure.

two。 Keep warm and frost-proof. If possible, emergency measures such as hot wire heating, candle lighting and smoke burning can be taken; open-field vegetables can be properly covered with straw, sunshade net and so on.

3. Reinforce the greenhouse to prevent collapse. Measures such as pillar reinforcement and snow removal should be taken in the shed, and emergency measures such as breaking film and protecting scaffolding can be taken if necessary.

4. Strengthen the field management after the disaster, and do a good job of ventilation, light and humidity reduction, disease prevention, thin application of foliar fertilizer and other measures to restore plant growth as soon as possible.

II. Fruit

1. Tree protection. The trunk can be painted white, and the trunk can be painted with quicklime, stone sulfur mixture, salt and water to set up pillars for young fruit trees and pruning fruit trees with too many branches.

two。 Shake the snow to reduce the damage. It is necessary to shake off the snow on the trees in time to prevent the snow from breaking the branches; to remove the snow from the greenhouse and other facilities in time to prevent it from crushing the greenhouse.

3. Timely treatment of broken branches, completely broken branches, should be sawed as soon as possible to smooth the wound, coated with wax and other protective agents; for the torn unbroken branches. Should first be lifted by rope or propped up, the injured area should be coated with wax and fastened to promote its healing and restore growth.

4. Strengthen cultivation management. Spray foliar fertilizer. Remove the stagnant water in the park in time. Control diseases and insect pests. Frozen trees are prone to diseases. Trim moderately. (see Li Ming, a reporter from Xi)
