Embodiment 1

[0045] 1. Investigation of the color change law and the location of colorful leaves during the development of colorful leaves

[0046] Observation found that the leaves of kiwifruit are light green in the first 1-2 days of growth, and begin to turn white in mid-May (after the buds appear), and turn into pink leaves in early June. Under artificial cultivation conditions, red leaves are prone to Photodamage phenomenon, the leaves that have undergone photodamage appear apoptotic gray-white leaves, commonly known as photobleaching leaves, while the leaves that have not undergone photodamage are light green. The position of leaves prone to photodamage is 4-15 nodes above the fruiting branch.

[0047] 2. Determination of net photosynthetic rate

[0048] 2.1 Determination method

[0049] Net photosynthetic rate (Pn) and other photosynthetic parameters were measured with reference to Wang et al. -2 ·s -1 , CO 2 Concentration = 380μmol·mol-1 , the relative humidity is 70%, the gas...

Embodiment 2

[0054] 1. Measurement method

[0055] The determination of photosynthetic parameters such as net photosynthetic rate (Pn) refers to the method of Wang et al. (2012), using a portable photosynthetic instrument (CIRAS-2; PP-Systems, USA), light source LED, PAR=1200μmol·m -2 ·s -1 , CO 2 Concentration = 380μmol·mol -1 , the relative humidity is 70%, the gas flow rate is 196mL·min -1 . Each leaf was measured for about 3 minutes, and recorded after the value was stable.

[0056] Shade the leaves under full sun conditions on the sunny side at the beginning of June when the leaves start to turn red, and use black shading nets with a shading rate of 10%, black shading nets with 20%, and black shading nets with a 30% shading rate respectively. Shade net, 40% black shade net, about 20 days after shading, measure the color leaves and green leaves under 10%, 20%, 30%, 40% shading conditions. The measurement was carried out at 9:00 to 10:00 in the morning on a sunny day. The selected...

Embodiment 3

[0061] Respectively at the beginning of June when the leaves begin to turn red, shade the leaves under the condition of full sun on the sunny side, and adopt black shading nets and 15% black shading nets with a shading rate of 10% respectively for shading.

[0062] It was observed that none of the leaves were damaged by light.

Abstract

The invention relates to the field of fruit tree cultivation, in particular to a cultivation method of actinidia kolomikta. When leaves of the actinidia kolomikta start to go red, 5%-15% of shading net is adopted for shading. On the basis of determining the colored leaf occurrence space and time rule, the method aims at the situation that the photo damage phenomenon of color leaves is likely to happen at the development later stage, so that the leaf photosynthesis efficiency is affected. The method is characterized in that the occurrence period and the occurrence position of the color leaves of the actinidia kolomikta are investigated for the first time, on the basis of understanding the occurrence rule of the colored leaves, the photosynthesis efficiency of the colored leaves under different shading degree conditions is measured from the perspectives of the photosynthetic rate and the photochemical activity through shading in the key period when photo damage is likely to happen, the shading degree through which photo damage of the colored leaves can be avoided and the photosynthetic rate cannot be reduced is screened out, therefore, the high photosynthesis efficiency of the colored leaves can be kept within the whole growth period, and it is avoided that photo damage of the colored leaves is generated, so that the leaf photosynthesis efficiency is seriously reduced and even lost.

Description

technical field [0001] The invention relates to the field of fruit tree cultivation, in particular to a method for cultivating kiwi fruit. Background technique [0002] Actinidia kolomikta (Maxim.&Rupr.) Maxim.] is a perennial vine of the family Actinidiaceae, and is an important fruit tree resource in my country. Its fruit is rich in nutrients, and its Vc content can reach 634mg / 100g (Lu Juan, 2009; et al., 2014), known as "super fruit". An important biological feature of Actinidia kiwifruit is the growth of a large number of colorful leaves. During the flowering period, the number of white leaves accounts for up to 85% of the total leaves on the new shoots (reproductive branches), and the average value can reach 59%. Therefore, the crown of the tree during the flowering period Layer leaves are mainly composed of white leaves. Under artificial cultivation conditions, these colorful leaves are easily damaged by light in the middle and late stages of growth, which serious...
