Greenhouse vegetables should be how to deal with h
[2016-1-26]

The following measures should be taken to address the impact of the snow on the vegetables:

1, timely rush in the market. Cold weaker cabbage and other vegetables to seize the waist tied freezing measures taken, but also the use of shade nets superficial covering insulation, and can be frozen vegetable timely rush in the harvest, stored indoors, listed in batches.

2, do the antifreeze warm. For snow weather, pay attention to strengthening the greenhouse facility, you can take the studio set up a pillar reinforcement, snow removal and other measures, a personal management and protection, in addition to snow in the evening to timely grilled on greenhouse to prevent the snow is too thick collapsed greenhouses, can be taken when necessary Paul rupture scaffolding and other emergency measures; early closed greenhouses, stamped cover; check leaking, to prevent cold air into the shed. Areas where conditions permit should take a multi-layer overlay, in plastic shed built shed or hut, and cover straws, woven or shade net warming; field vegetables can be superficial covering straw, shade net, mitigate frost damage It occurred. Rain and snow continued to take advantage of relatively high temperature at noon Jiemo see the light, after the weather turned for the better done sooner or later, Qin Jie ground cover, consecutive rainy days suitable fill light warming.

3, pay close attention to clear the drainage ditch. For high water table grapes and other vegetable fields or orchards, to seize a good start "Three ditch" to ensure smooth Gully, in order to timely exclude water, lowering the water level, improve soil temperature, and promote growth. Timely removal of snow sheds; after the rain and snow, to promptly clear the ditch, the lower temperature of the snow melt water discharged outside the field as soon as possible, in particular, to prevent melting snow intrusion into the shed.

4, reasonable earth fertilizer. After the rain and snow, loose soil should be promptly earth, improve soil temperature, root protection, the line between conditional applicator still thin rice husk ash, ash and the like. To control the use of vegetables appropriate to reduce the amount of nitrogen fertilizer, seedling stage, avoid partial nitrogen, in order to increase the resistance, and focus on foliar fertilization, sunny foliar spraying after 1 or 2 times 0.2% of potassium dihydrogen phosphate solution enhance antifreeze capability. Amenities vegetables to enhance ventilation see the light, plants are growing resume as soon as possible.

5, strengthen seedling management. Greenhouse cultivation Solanaceae, melons and other vegetable shoots, to do weatherization measures, the case of low temperature stunted, increase light shining, graced warming, in order to promote growth. Cold weather seedbed to control the watering, do not pour nutrition soil not white. Conditional use of electric wire and other heating facilities, and promptly built a small shed, cover non-woven fabric. To be broadcast vegetables seedlings, should avoid cold damage by increasing geothermal and other measures before sowing.

6, and remove snow. In case of rain and snow, should be promptly removed Zhigan grapes, leaves and snow field, and to seek out external field, to prevent a large number of snow melting temperature drop caused by the Land to make the like grapes and vegetables subject to more severe low-temperature damage.

7, strengthen management after freezing. Vegetables frozen vulnerable to pests and diseases, should be promptly spray iprodione, chlorothalonil, metalaxyl Mn-Zn fungicides to prevent disease, and timely topdressing fertilizer. Rain and snow humidity within the greenhouse when not spraying, the choice fumigant and disease prevention to reduce greenhouse humidity. Prone to frost vine diseases, according to different degrees of frost damage suffered timely and appropriate pruning, have been frozen withered branches, pruning should take two steps, the first cut has been clear dead branches, sprout and then be cut off from life and death junction twigs.
