The soil requirements for kiwifruit are non-alkaline, non-clay soils. For example, mountain meadow soil, mountain yellow soil, mountain yellow-brown soil, mountain brown soil, red soil, yellow soil, brown soil, yellow-brown soil, yellow sandy soil, black sandy soil, and various kinds of sandy and gravelly soil can be cultivated. However, high humus content, good aggregate structure, strong soil water holding capacity and good aeration are most desirable. The Chinese and Delicious kiwifruit grows and develops well on soils with a pH of 5.5-6.5, containing 0.12% phosphorus pentoxide, 0.86% calcium oxide, 0.75% magnesium oxide, and 4.19% iron trioxide. They can also grow on neutral (pH 7.0) or slightly alkaline (pH 7.8) soils, but yellowing often occurs during the seedling stage and growth is relatively slow.
In addition to soil quality and pH, the mineral nutrients in the soil also have an important effect on the growth and development of kiwifruit. In addition to the need for nitrogen, phosphorus, potassium, kiwifruit also need rich magnesium, manganese, zinc, iron and other elements, if the soil lacks these mineral elements, in the leaves often show nutritional disorders of deficiency. Kiwifruit has a higher demand for iron than other fruit trees, requiring a critical value of 11.9 mg/kg of effective soil iron, compared to 9.8 mg/kg and 6.3 mg/kg for apples and pears, respectively. Iron in the soil pH higher than 7.5, the effective value is very low, so alkaline soil cultivation kiwifruit, pay more attention to iron fertilization.
