Spring is here, although the weather is getting warmer and warmer, but there will also be a phenomenon of “spring coldâ€, which will seriously affect the yield of cherries. So, how does cherries prevent the “cold spring†hazard?
Cherry flowering period is very strict with temperature, suitable temperature is about 15 °C, night should be kept at 8-10 °C, the lowest temperature is not lower than 5 °C, the temperature is too low during flowering, which is not conducive to pollination and fertilization, weather below 0 °C Will destroy the tissue cells of cherry flowers, directly affecting the quality and fruit setting rate of the cherry.
Prevention and rescue measures for cherry cold spring:
The greenhouse cherry is in the late flowering stage and the initial stage of fruit setting. For the frozen cherry trees, it is necessary to topdress, spray antifreeze, strengthen pest control, and strengthen the leaves. Protect the normal development of flower bud differentiation to reduce the extent of yield decline caused by freezing damage and promote the robust growth of trees. For the cherry trees that are seriously damaged, appropriate cuts should be taken to supplement the cuts to enhance the growth of the trees.
The field cherry trees have not yet flowered, and should be timely flooded in early spring, lowering the ground temperature and delaying the flowering time of the germination; it can also carry out measures such as fumigation and frost protection, tree spraying, topdressing, etc., combined with spring fertilization for deep turning of the orchard to promote fruit trees. Growth, improve the resistance of the tree.
