Problems solved by technology

Due to the low survival rate of thorny grape cuttings (survival rate is about 15-20%), layering and tillering are used in current production to breed and raise seedlings. Therefore, the propagation speed is slow and the efficiency of seedling raising is low, which cannot meet the needs of thorny grape production.

Embodiment Construction

[0011] Step 1 of the present invention is to collect and sterilize: it is better to select sunny days for the cuttings collection time in mid-January, and it should not be later than the end of January (after the end of January, the thorn grape sap starts to flow, and when the branches are cut, the sap will flow out. cause nutrient loss and reduce the survival rate of cuttings). When collecting, choose an annual with a diameter of 0.8 cm or more (cuttings below 0.8 cm are not easy to take root and have a low survival rate), with full bud eyes and full mature branches. When cutting, remove the tendrils, auxiliary shoots, and fruit stalks, soak and soak with 70% thiophanate-methyl 800 times + 40% phoxim 1000 times (the purpose is to sterilize the cuttings, eliminate the source of diseases and insect pests, and reduce the number of cuts after cuttings). Diseases and insects occur) to kill the diseases and insects on the cuttings, take them out and dry them for later use.

Abstract

A root-promoting and cutting seedling culture method for Fu'an brier grapes includes the steps of firstly, collecting and sterilizing, wherein collecting time is set before the end of late January; secondly, cutting cuttings; thirdly, performing dipping treatment; fourthly, performing root-promoting culture in a hotbed, wherein a seedling culture bed is set as that a first layer is formed by spreading rice husks or sawdust 10cm in thickness and covering with a mulching film, a second layer is formed by covering the mulching film with fine sand 5cm in thickness and laying soil heating lines on the fine sand, and a third layer is formed by spreading sandy vegetable garden soil 15cm in thickness and with 60%-65% of moisture content, the temperature of the hotbed is controlled between 25 DEG C and 28 DEG C, the moisture content of the hotbed is controlled between 60% and 65%, indoor room temperature is controlled to be 10 DEG C, humidity is controlled between 50% and 70%, a callus is formed after promoting a root for 18-22 days, and after promoting the root for another 9-11 days, entering a step five of transplant and greenhouse culture in late February when the new root grows 1-2cm taller; fifthly, performing transplant and greenhouse culture, namely, continuing culture until five leaves sprout prior to outplanting. By the aid of the root-promoting seedling culture technology, seedling culture survival rate is increased to be 75%.

Description

Technical field: [0001] The invention relates to grape propagation technology, in particular to a method for promoting roots and cutting seedlings of Fu'an thorn grapes. Background technique: [0002] Fuan thorn grape is a wild thorn grape that has been cultivated and domesticated. It has the advantages of low acid content, sweet flavor, resistance to diseases and insect pests, resistance to extensive management, resistance to high temperature and high humidity, and storage and transportation. It is the best wine-making variety among East Asian populations; The content of resveratrol and proanthocyanidins in its fruit is much higher than other varieties in the population. On May 22, 2014, Fuan thorn grapes obtained the registration of geographical indications of agricultural products from the Ministry of Agriculture, allowing the use of public marks of geographical indications of agricultural products on agricultural products or agricultural product packaging (registration c...
