Kiwi is a crop that is neither drought-tolerant nor heat-tolerant, and is extremely vulnerable to dry heat. Kiwi planting has the following measures to cope with high temperature weather:
Irrigate in a timely manner. In high-temperature weather, you should irrigate frequently, use all water sources to pay close attention to irrigation, and keep the soil moisture in the orchard. Conditional parks should strengthen the construction of irrigation measures such as sprinkler irrigation and drip irrigation during the construction of the park. In areas with insufficient water sources and prone to high temperature and drought hazards, it is necessary to strengthen water management in critical periods to make up for insufficient precipitation. Irrigation time should be selected before 11 a.m. and after 17 p.m. to prevent tree and fruit burns.
It is an effective measure to increase the drought resistance and water-saving cultivation of trees by covering grass reasonably during the period of high temperature and drought. Orchard grass can not only reduce water evaporation, keep the soil moist, loose, stabilize the ground temperature, and protect the normal growth of the root system, but also prevent soil compaction and weeds, reduce the number of tillage times, and effectively improve the garden microclimate.
Pruning sparse fruit adult trees should be properly wiped buds, when the branches grow to 40 ~ 50 cm topping. Wipe the buds and topping once every 7 to 10 days to help the branches become full and aging, reducing water transpiration. In case of continuous high temperature weather and the water source cannot be guaranteed, in order to prevent the plant from dying due to drought, one is to appropriately increase the amount of pruning in summer to reduce the water transpiration of the tree; the second is to shed a lot of fruits to reduce their competition for nutrients and water.
