Loquat seedling planting standards

Temperature: The subtropical climate of the origin of loquat requires a relatively high temperature. Normal growth and development can be achieved if the annual average temperature is above 12°C, but it is necessary to carry out economic development planting. The annual average temperature is 15~17℃, and there are no cold temperatures. Loquat blooms in late winter and early spring, and ultra-low temperatures in spring and winter will affect its fruiting.

Soil: For loquat planting, it is advisable to select high-yield upland fields with flat, thick, loose, fertile soil and organic matter. A soil pH of 6.0 is the most suitable. Water resources must be taken into consideration in site selection to ensure The plantations can be irrigated from November to May of the following year, and transportation and transportation are convenient. It is not suitable to select land where the terrain is low and easy to retain water. Before planting, it should be plowed deeply and thoroughly for more than 30 centimeters.

Seedling stage selection: The seedling base site should be selected from the shady side and downwind, loose soil, containing organic matter, medium fertilizer efficiency, sandy soil with good soil retention and water retention. Approximately ten days before sowing (early May), apply appropriate retting compost, soil machine fertilizer, manure or 50KG compound fertilizer per acre as base fertilizer. Then the soil is plowed, and the furrows are made finely and flatly. Each furrow is 1.2 meters wide and the furrow is 30cm. Where there are underground pests, carbofuran should be used to disinfect the soil before plowing to kill underground pests.

Seed selection: Loquat seeds are not dormant. Before planting, the loquat cores must be selected to remove small and abnormally growing loquat seeds. Use large, round loquat seeds that have been washed and dried. Then you can sow.

Sowing method: The sowing period is from mid-to-late May to early to mid-June. There are two sowing methods (generally drill sowing is used). The spacing between rows is 20-25cm, and the spacing between plants is 10-12cm. Depending on the seed survival rate, sow 1-3 seeds in each hole. Squeeze when sowing, press half of the seeds into the ground, and sprinkle fine soil on the ground. Take it as a measure that you can’t see any loquat seeds. If the seeds are sown too deep, it will not only be difficult to excavate, but also cause mold. If they are sown too shallow, they will not be planted. How to maintain and manage loquat saplings?

The investment in liquid fertilizer is small in the sapling stage. If there is less fertilization and watering, and the growth is slow, the nutrients of the sapling will not be enough to meet the chemical requirements of the flowering stage. For this kind of "starving" saplings, liquid fertilizer should be added to improve their health before they can be harvested at the right time. Unreasonable pruning. For saplings, if pruning is done once a year and the pruning is too heavy, it will inevitably cause yellow leaf disease, unstable plant shape, and inability to bear fruit. The pruning of saplings should be with the clear goal of plastic surgery, with the purpose of increasing branches and crowns and stabilizing the plant shape.
