What planting density is suitable for pear trees? Key points for rational close planting
Abstract The planting density of pear trees can be determined according to the variety type, tree size, planting technique, climate environment, soil environment, and root growth environment. Generally, for varieties with a large canopy, many branches, and vigorous growth, the planting density can be based on a plant-to-row spacing of 4-5m, planting about 30 trees per mu. Varieties with a small canopy and few branches can be appropriately planted more densely, based on a plant-to-row spacing of 3-4m, planting about 50 trees per mu, while varieties with a very small canopy can be planted even more densely.

Correct Methods and Steps for Planting Sweet Potatoes by Cutting into Pieces
Summary Early land preparation: In winter or early spring, form ridges according to the terrain, and per mu apply an appropriate amount of organic fertilizer, ammonium bicarbonate, superphosphate, and potassium sulfate. Select seed potatoes carefully: choose tuber pieces weighing 100-150 grams. Cut into pieces and soak the seed: soak the tuber pieces in a carbendazim solution. Sow and cover with film: avoid frost damage. Break the film to release seedlings: when the seedlings grow to 3 cm, manually break the film. Scientifically fill in seedlings: replant where seedlings are missing. Timely clear the plants: keep 2 strong seedlings per plant, and cut off all the rest.

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.
