Agricultural activities in heavy snow

Main agricultural activities in the solar term of heavy snow;

1, sparse seedlings

Direct-seeded rape, especially on-demand rape, due to the dry weather, the sowing amount is too large, the emergence is uneven, and the phenomenon of lack of seedlings and broken ridges is common. We should pay close attention to thinning seedlings and avoid squeezing seedlings to form weak seedlings. It is necessary to go small and stay big, plant the missing seedlings, bring water when replanting, and promote early survival.

2, intertillage, ridging

Intertillage has many functions, such as warming, preserving soil moisture, weeding, preventing pests and diseases, loosening soil and promoting root growth. Therefore, the rape field should be cultivated diligently. Combined with intertillage, soil cultivation, especially high seedlings, can not only reduce freezing damage, but also prevent lodging. Pay attention to bury all the high feet, especially the root neck.

3, topdressing wax fertilizer

Rapeseed topdressing is mainly soil mixed fertilizer. Combined with the last intertillage before winter, rape roots can be fertilized, which can be topdressing first and ridging again. You can also sprinkle plant ash, water and fertilizer.

4. Cover with antifreeze

Straw mulching can prevent freezing and inhibit the growth of weeds. After the straw is decomposed, it can improve the physical and chemical properties of soil, improve soil fertility and improve the environment. For direct sowing rape and late sowing rape, straw can also be evenly covered between rape rows.

5. Remove early moss

Due to the high temperature in autumn this year, early transplanted rape and spring varieties are prone to early moss, so they should be picked as soon as possible. Moss picking should be carried out on sunny days, and growing points should be picked to inhibit the growth of main stems and promote the growth of branches.

6, chemical control

Spraying 40 kg of water with paclobutrazol (PP 338+05% PP 338+000g/ mu) before overwintering in the rape field with early sowing, vigorous growth and futile growth trend can control vigorous growth and prevent freezing injury.

7. Clean up the "three ditches"

For those who have already opened the "three ditches", it is necessary to dredge the ditches. No, it is necessary to open the "three ditches" and connect the ditches, which is conducive to irrigation and drainage in the coming year.

8, fruit tree pruning, garden closure

Most fruit trees are dormant in winter and still need to be managed and pruned. Young trees should also do a good job of pulling branches, and through pruning in winter, the crown will be cultivated into a reasonable high-yield tree. Reasonable garden closure can effectively reduce the overwintering base of orchard pests and diseases. Deciduous fruit trees can remove dead branches, diseased leaves, hard fruits and residual leaves from orchards after pruning in winter.

9. Animal husbandry and agriculture

Conduct a comprehensive overhaul of livestock and poultry pens to improve the temperature in the pens; It is not suitable to feed frozen feed and cold water; Cattle, sheep and herbivores should be properly supplemented with concentrated feed and artificial pasture; Pay close attention to the epidemic situation and do a good job in disinfection and isolation of livestock houses.
