Detailed Explanation of the Key Technical Points and Operation Methods of the Second Film-Covering Technique for Garlic
Adopting a double-layer plastic film mulching cultivation technique for garlic can increase yield, bring it to market earlier, and boost profits. Below, the editor will introduce the second film-covering technique for garlic. 1. Second film-covering technique for garlic: When covering with film, the plastic film is required to lie flat on the bed surface without wrinkles, with no gaps beneath the film, so that the film fits tightly against the bed surface and weeds are prevented from growing. When more than 50% of the garlic has emerged, break the film by piercing holes in it with a sharp iron wire, keeping the hole diameter at about 1 cm.

Key Technical Points and Operation Methods of Vegetable Grafting Explained
Abstract Top-insertion grafting method: Pull the bamboo skewer inserted in the rootstock out, then insert the trimmed scion into the hole, with the scion cotyledons and rootstock cotyledons forming a "cross" shape.
