Flower seedlings in the snow after the remedial measures

To reduce the snow and the cold air on myflowers, nursery stock production effects, the freezing snow damage and losses to a minimum, the production units and growers should focus on the following aspects:

First, greenhouse management.

Being collapsed, there should be an immediate collapse of the deformation of the canopy reinforcement and repair, can not be repaired, and timely transfer to shed plants, or stamped film, straw mat or shade net, improve the insulation effect. Second, after the freezing snow to do the work. Snow, freezing weather will occur in various types of greenhouse shed endometrium should be added to form a film inside and outside the insulation layer, heating conditions should be shed. Of greenhouse flowers, timely removal of sick leaves, for disease prevention and control. Small Shed, replace broken arch, fill or for plastic sheeting.

Second, management in open flowers.

Of seedlings exposed to lodging, the head of the CIA saw in addition to snags, not righting or cut altogether too small size. After the snow melted earth to strengthen roots and increase in temperature. Areas where conditions permit coverage can be taken to reduce frost damage. Should also make clear the drainage ditch around the nursery, reducing field soil moisture, snow water to avoid the garden to prevent frost damage and waterlogging occur simultaneously, frostbite roots. Of seedlings and ground cover plants should be taken to superficial straw, shade nets and other measures to prevent frost damage.

Third, the recovery after freezing measures. Plants under cultivation and management to strengthen after freezing in order to restore tree vigor.

1, frozen in time after drainage, can ease the impact of frost damage, reduce losses, after re-frozen tree in the bud, but also to pay attention to the management of soil moisture, over floods, drought is not conducive to plant growth over the recovery.

2, the implementation of earth and inter-row cover. After the snow, you can plant four Zhou Zengpei new soil, and use firewood, straw, grass, leaves, wood saw dust, manure, rice and wheat shell lemma, straw bedding in the seedbed before frozen soil to increase soil insulation.

3, according to the degree of frost damage, and reasonable treatment crown. After the freeze is still a good shoot, but do not drop leaves wilt, should be promptly removed.

4, the cold light of the plants, the occurrence of leaf, yellow leaves, grow weak, the available foliage spray of 0.5% urea for 2 to 3 times, after the spring thaw, adequate facilities for early spring fertilizer to restore its growth potential . Re-freezing plants, should be thin and more fertilizer facilities, with particular attention to control fertilization period, in order to promote the spring, summer shoot and control the fall tree for the purpose. In addition, after the frostflowers growing weaker, often lead to diseases and insect pests, must always check and do pest prevention.
