The drought resistance of 1 monkey peach is worse than that of common fruit trees. Kiwi has large and dense leaf shape, large transpiration and large water demand. According to the calculation, the adult kiwi fruit tree with a canopy area of 25 square meters loses more than 75 liters of water by transpiration every day. Fruit trees with weak physiological drought tolerance and weak humidity tolerance have strict requirements on soil moisture and air humidity, which determines that kiwifruit is most suitable for planting in areas with abundant rainfall, uniform distribution, high air humidity and moist but not waterlogging.
Kiwifruit is quite weak in wind resistance and vulnerable to wind damage. The main reason is that its leaves are large and inelastic. Strong winds break shoots, leaves break, and fruits are bruised or shaken, thus reducing yield and commodity performance. Therefore, the mountain garden construction should try to avoid choosing the windward mouth, ridge and windy area at the top of the mountain, and should choose the leeward slope with the direction of early sunny slope and late sunny slope. Slightly acidic sandy soil with deep fertility, good air permeability, groundwater level below 1 m, high organic matter content and PH value of 5.5-6.5 is suitable, and strong acid or strong alkali soil can be planted only after it is improved.
Under natural conditions, kiwifruit is mainly pollinated by insects. Artificial pollination is also one of the important agricultural measures in orchards with abundant labor resources and fine management. A large number of artificial pollination practices show that the better pollination, the more seeds, the bigger fruits and the better quality. Don't pile up flowers after picking. Store in small batches in breathable bags or cardboard trays in the shortest time, and put them in a cool and dry place away from the sun. Kiwifruit has dense branches and leaves, shallow root distribution, and is neither drought-resistant nor waterlogging-tolerant, so Kiwifruit Garden needs irrigation and drainage equipment such as irrigation canals, drainage ditches, drip irrigation and sprinkler irrigation equipment. Economic water is drip irrigation, and the water supply is uniform; Sprinkler irrigation needs a lot of water, but it also plays a great role. In summer, sprinkler irrigation can not only supply water for roots, but also increase air humidity and reduce the temperature of trees. Sprinkler irrigation has antifreeze effect in early spring and autumn and winter.
The flowering period needs a slightly dry climate, which is beneficial to bee pollination. Therefore, 7- 10 days of flowering is not suitable for irrigation, but should be fully irrigated before flowering, generally combined with fertilization. Pay attention to drainage in rainy season, and control irrigation in autumn after rainy season, so as not to affect the ripening of fruits and vines. Irrigation is required 1-2 times before winter in late autumn. In the northeast, water should be frozen. Before flower bud, use 3-5 baumeishi sulfur mixture or 500 times solution of 65% zineb wettable powder.
