Problems solved by technology

However, there is a lack of systematic research on grafting rootstocks, grafting methods, cultivation conditions and quality control, resulting in a low survival rate of grafting, serious dead and rotten trees, and is far from meeting the needs of industrialized production of grafted seedlings.

[0011] Example 1: Determination of Seedling Culture Substrate for Promoting Cucumber Grafting Wound Healing Rapidly

[0012] From January to April 2019, the rapid healing experiment of cucumber grafting wounds induced by arbuscular mycorrhizal fungi was carried out in the Seedling Center of Henan Modern Agriculture Research and Development Base. 3 treatments were established in the test: treatment 1, seedling-raising substrate; treatment 2, commercial substrate (Luqing substrate); treatment 3, self-combination substrate ck (peat soil: vermiculite: perlite=6:1:3, add 0.5% brown sugar, 0.2% Potassium dihydrogen phosphate and 1% P. lilacinus inoculum (pt361, number: CCTCCM2016681)). Each treatment of 15 hole trays (40 holes / sheet hole tray) was 1 repetition, and was repeated 3 times, that is, 45 sheets of each treatment, 1800 grafted seedlings. The black seed pumpkin is the rootstock, the cotyledons are fully unfolded, and the grafting is carried out when the plant height is 4cm...

Abstract

The present invention relates to a seedling culture matrix as a healing promoting agent for promoting quick healing of a cucumber grafting wound and an application thereof. A matrix formula comprisesgrass carbon, perlite and vermiculite with the ratio of 6:3:1, and 0.5% of brown sugar, 0.2% of potassium dihydrogen phosphate and 1% of a purpureocillium lilacinum agent (pt361 and number: CCTCCM2016681) are added, so that the matrix can be developed into the healing promoting agent for promoting quick healing of the cucumber grafting wound; and compared with different healing promoting agents atpresent, the healing promoting agent has the characteristics of shortening quick healing time of the wound, preventing diseases and strengthening seedlings. The strain disclosed by the invention notonly promotes quick healing of the cucumber grafting wound, but also improves the seed germination rate, promotes the growth and shortens the commercial seedling period.

Description

technical field [0001] The invention belongs to the technical field of microorganisms, and in particular relates to a seedling-growing substrate for promoting the rapid healing of cucumber grafting wounds and an application thereof. Background technique [0002] Cucumber is an annual vine or climbing herbaceous plant of Cucurbitaceae, also known as courgette and cucumber. It is a widely cultivated vegetable variety in the world, and it is also one of the most important vegetable crops in the world, with the largest facility cultivation and the highest economic benefits. In 2017, my country's facility cucumber sowing area was about 9.4 million mu, while the perennial cucumber sowing area in Henan Province was about 2.55 million mu. With the adjustment of the agricultural industrial structure, the cultivated area of ​​protected vegetables in our country is increasing continuously, and the production of protected vegetables is developing in a large-scale, specialized and indust...
