Classification after vegetable remediation
The large-scale ice and snow disaster has delayed vegetables in the greenhouses (such as greenhouse peppers, eggplants, tomatoes), winter vegetables (such as cabbage, vegetable vines, and ma ling yam), and early spring vegetable seedlings (such as solanaceous fruits and melon seedlings). Such as serious damage, should be classified as a remedy.
First, we must effectively strengthen the management of vegetable seedlings to prevent freezing.
At present, greenhouses are mainly seedlings of pepper and other eggplant vegetables. For young seedlings that have been sown and seeded, measures such as multi-layer covering should be adopted. In the near future, it is best to cover straw insulation; second, less watering, lowering the shed The third is to prevent the occurrence of disease in a timely manner. Attention should be paid to the occurrence of damping-off and blight, and at the same time, cold exercise at the seedling stage must be strengthened to improve the cold resistance of the seedlings. After the seedlings emerge, the seedbed should be ventilated, and gradually increase ventilation with warmer weather. The seedlings should be subjected to low-temperature exercise to improve the cold resistance of the seedlings and to adapt to outdoor low-temperature environment.
For seedbeds that have already been victimized, decisive adoption of electric heating lines and other methods of raising seedlings will cull planted seedlings planted in spring, such as pepper, eggplant and tomato. We must pay attention to the production of early spring vegetables, and increase the variety and area, such as the organization and production of cucumbers, zucchini, and sprouts in melons, and strive to make up for the spring losses in the spring.
Second, we must comprehensively use the following measures to strengthen antifreeze management of wintering vegetables.
Increase farm manure. Warm farmhouse fertilizer such as pig cow dung or earth miscellaneous fertilizer, cultivating in the roots of vegetables, can increase the root soil temperature 2 ~ 3 °C, should be carried out on a sunny day, per acre Shi 1000 ~ 1500 kg. In combination with cultivator, the use of fine soil to cultivate the soil around the root can loosen the soil, increase the soil temperature, and protect the root directly. Must be carried out before the soil is frozen. The depth should be 5 to 10 cm.
Add foliar fertilizer. Foliar application of 1-2 times 0.2% potassium dihydrogen phosphate solution to the vegetables in the shed can not only supplement the plant nutrition, but also enhance the cold resistance.
Add a cover. On the afternoon of the frosty day, cover the vegetables and vegetables with agricultural film or wheat straw to reduce wind and cold damage. 100-150 kilograms of straw per acre, to be scattered, must not cover all the vegetables, so as not to affect photosynthesis.
Open the ditch to prevent waterlogging. In winter, the groundwater level in the field is relatively high, which may cause the roots of vegetables to freeze and die. By digging trenches, the groundwater level can be reduced and the growth of crop roots can be facilitated. Snow can easily cause the ditch to collapse. After the snow, it should immediately clear the ditch, remove the accumulated water, increase the vitality of the roots, and prevent the occurrence of waterlogging. To clear the snow on the shed. The snow on both sides of the greenhouse should also be removed in time to prevent absorption of large amounts of heat while melting to reduce the temperature inside the shed, and to drain water in time to prevent waterlogging.
In addition, we must take time to collect and market the grown food crops to minimize post-disaster losses. We must repatriate the waste crops in time and use them in order to improve soil fertility and kill pests in the soil. Source, lay a good foundation for spring production.
