High temperature weather attaches importance to kiwifruit fertilizer management
a small number of multiple points of scientific fertilization
The roots of kiwifruit are fleshy roots, which are shallowly distributed, and are highly susceptible to chemical fertilizer damage and mechanical damage. Lightly, the leaves, branches, and fruits are dehydrated and sunburned. In severe cases, the tree is weak and dead, and the kiwifruit is extremely harmful. Kiwifruit is fertile, but it is afraid of big fertilizer. The topdressing of the growing season should be carried out in small quantities. The amount of topdressing should not be too large. Fertilization should be applied to multi-point fertilization. When fertilizing, attention should be paid to the distance. It should not be too close to the main root and applied to the canopy. It is advisable to project the peripheral branches, avoiding the fertilization caused by fertilization. During the high temperature period, it should be fertilized first, then fertilized immediately after fertilization, and the conditional orchard can implement the integrated fertilization technology of water and fertilizer.
Avoid high temperature irrigation with bagging anti-sunburn
In the high temperature and dry period, water should be poured in time. From 12 noon to 4 pm on sunny days, too high temperature will lead to excessive transpiration of the leaves, while the water provided by the roots is difficult to meet the transpiration of the leaves, and the stomata of the leaves will cause wilting. If the orchard is dry, it should be avoided to fill the water at noon high temperature. When filling the water, it can be divided into small pots. The conditional orchard can use drip irrigation and sprinkler irrigation to avoid flooding.

The drainage pump is often used for urban waterlogging, rural and forest fires to prevent and deal with emergencies. It supplies water to the fire site through pressure pipelines or fire monitors, and can also be used for drainage when large-scale flooding occurs.
When there is a considerable distance between the ponding point and the drainage site, the supplementary pipe can be used to extend to 1000m to realize long-distance drainage. When there is water, it can replace the fire truck and be used as the pump station. Equipped with hydraulic bit, it can extinguish peat fire and also can use fire monitor.
