Embodiment 1

[0023] A method for growing seedlings of kiwifruit by cuttings, the specific steps are as follows:

[0024] (1) Cutting substrate preparation: Mix peat soil, perlite, and fine sand at a volume ratio of 1:2:2 to obtain the cutting substrate; transfer it to a 4×8 hole tray (32 holes), and the length of the hole tray is 54cm , width 28cm, height 60mm; use carbendazim 50% wettable powder 1000 times liquid to pour through the cutting matrix, and sterilize for 24 hours;

[0025] (2) Selection of cuttings: select plants with good growth in spring or summer, select lignified or semi-lignified twigs and branches, and cut them into cuttings with a length of 10-20cm; keep 3-4 buds in the cuttings;

[0026] (3) Pre-treatment of cuttings: put the cut cuttings into clear water, the depth of clear water is 5-8cm, and soak for 12 hours; when soaking, keep all the leaves first, and when the soaking ends, keep one leaf or half of the leaf at the top bud, and the rest cut off;

[0027] (4) Cut...

Abstract

The invention discloses a method for cuttage breeding of actinidia valvata, and belongs to the technical field of agricultural planting. The method for cuttage breeding of actinidia valvata disclosedby the invention comprises the following steps: (1) cuttage medium preparation; (2) cutting selection; (3) cutting pretreatment; (4) cuttage; (5) management after cuttage. The method of the inventioncan effectively increase the rooting rate of cuttage, and the rooting rate can reach 100%; through the cuttage breeding method of the invention, actinidia valvata seedlings with consistent growth vigor and relatively high anti-water-logging ability and salinity and alkalinity resistance can be bred; the actinidia valvata seedlings can be used as special rootstocks; the quality of the actinidia valvata seedlings is improved; and the method has relatively good application prospects.

Description

technical field [0001] The invention relates to the technical field of agricultural planting, in particular to a method for growing seedlings of kiwifruit by cuttings. Background technique [0002] Kiwi fruit is widely favored for its unique flavor, rich in vitamin C, various mineral nutrition, and functions such as clearing the intestines and strengthening the stomach, and has become one of the important fruits. my country is the birthplace of the vast majority of Actinidia Lindl. germplasm resources, and the cultivation area of ​​Actinidia Lindl. in my country ranks first in the world. At present, most of the kiwifruit seedling breeding adopts the seedlings of delicious kiwifruit as rootstocks, which have many disadvantages, such as the poor consistency of seedling growth, and the seedling stock itself has poor salt-alkali resistance and waterlogging resistance. Therefore, choosing rootstocks with good resistance and growth has become The key to improving the quality of k...
