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. Approach grafting method: Insert the scion cut into the rootstock stem cut, the two cuts need to fit tightly together, then use a grafting clip ⟦4 <p class="cintro"><span>Abstract</span>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.

Cleft grafting method: Insert the trimmed scion into the cleft, keeping the rootstock and scion surfaces level, then use a grafting clip for securing.</p> <p></p> <p><strong>I. Vegetable Grafting Techniques</strong></p><p>1. Top-insertion grafting method</p><p>(1) Removing the rootstock growing point: A blade or bamboo skewer can be used to cut off the true leaves and growing point of the rootstock.</p><p>(2) Cutting the rootstock: A bamboo skewer with the same thickness as the scion hypocotyl and a wedge-shaped tip can be used, then insert it at a downward slant from the main vein of one cotyledon of the rootstock toward the other cotyledon to a depth of 1cm; generally, it is best if the outer epidermis is not pierced and the bamboo skewer is faintly visible.</p><p>(3) Cutting the scion: At 1-1.5cm below the cotyledon node, use a blade to cut it into a wedge-shaped face with a bevel length of 1cm.</p><p>(4) Grafting: 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.</p><p></p><p>2. Approach grafting method</p><p>(1) Removing the rootstock growing point: A blade or bamboo skewer can be used to cut off the true leaves and growing point of the rootstock.</p><p>(2) Cutting the rootstock: At 0.5-1cm below the cotyledons, use a blade to make a downward slanting cut, with the depth needing to reach 1/2 of the stem thickness.</p><p>(3) Cutting the scion: Make an upward slanting cut at the corresponding part of the scion, generally with the depth reaching 1/2 of the stem thickness, and the cut length the same as the rootstock cut.</p><p>(4) Grafting: Insert the scion cut into the rootstock stem cut, the two cuts need to fit tightly together, then use a grafting clip to secure the joint.</p><p>(5) Root cutting: After grafting, plant the rootstock and scion together into a nutrient pot, about 1cm apart, with the joint about 3cm from the soil surface; wait 7 days for the joint to heal, then cut off the scion root; generally after 10-15 days, the grafting clip can be removed.</p><p></p><p>3. Cleft grafting method</p><p>(1) Removing the rootstock growing point: A blade or bamboo skewer can be used to cut off the true leaves and growing point of the rootstock.</p><p>(2) Cutting the rootstock: From between the 2 cotyledons, split the young stem downward, with a length of 1-1.5cm.</p><p>(3) Cutting the scion: Cut the scion young stem into a wedge shape, with a cut surface length of 1-1.5cm.</p><p>(4) Grafting: Insert the trimmed scion into the cleft, keeping the rootstock and scion surfaces level, then use a grafting clip for securing.</p><p></p><p><strong>II. Suitable Grafting Time for Vegetables</strong></p><p>1. Cucurbits: When the cotyledons are fully expanded and when the true leaves appear, this is the suitable grafting period.</p><p>2. Eggplant: When the rootstock has grown 3-4 true leaves and the scion has grown 2-3 true leaves, grafting requires retaining 1 true leaf.</p><p>3. Tomato: When the rootstock has grown 4-5 true leaves and the scion has grown 2-3 true leaves, grafting requires retaining 1 true leaf.</p>

A Detailed Explanation of Corn Seedling Raising Methods and Key Technical Points
Summary Seedbed seedling raising: spread nutrient soil into a seedbed surface, then scatter the seeds on the seedbed surface and cover with soil; when transplanting, lift the seedlings together with the soil. Nutrient cup seedling raising: use cup-shaped containers or a pot-making machine to make the nutrient soil used for raising seedlings into nutrient cups, then sow and raise seedlings in the nutrient cups; after the seedlings are grown, transplant them together with the cups. Soilless seedling raising: use wooden boards or other containers to make seedling trays, and raise seedlings in the trays by hydroponics.
