Planting and cultivation experience of Lemon

The main results are as follows: 1. Lemon is native to the lower layer of tropical forest and is a small shrubby tree with irregular branch growth and poor cold tolerance and is a semi-negative plant. Water conservancy and soil conditions must be taken into account in the selection of planting sites, and two slopes with convenient transportation, leeward to the sun, deep soil layer, fertile soil, flat land with drainage and irrigation conditions, gentle slopes or high-ridge paddy fields with elevations between 800 and 1200 meters above sea level and slopes below 30 °should be selected.

2. For seedling cultivation, wild sour rafters, Fructus Aurantii and red tangerine are selected as rootstocks, sown before the Beginning of Spring, transplant in seedling bed from May to early June, timely strengthen water and fertilizer management and pest control, eliminate weeds, and ensure that grafting begins in late November. The stem diameter of the rootstock is more than 0.4cm, and the best grafting time is from late November to the end of February of the following year. It reaches the standard of strong seedling and large seedling, the diameter of dry stem is more than 0.8 cm, and the height of seedling is more than 40 cm. Third, planting time lemons are evergreen fruit trees, which could have been planted all the year round, but the ancients said, "when there is no time to plant a tree, do not let the tree know." this means that the planting time is not immutable, and the key is not to damage too many roots. Therefore, according to the growth law of lemon, the planting time of lemon should be completed before March 10, dig the planting hole before the first ten days of April, return to the good pond before the first ten days of May, and end the planting from the first ten days of June to the end of June. Fourth, planting requirements 1. The planting pattern and density of lemon trees are different from other tall fruit trees. 64 trees are planted per mu, and the row spacing is 3.0 × 3.5 meters. The pond gauge is 80 × 70 × 60 cm, the slope should be the whole set, the topsoil and raw soil should be stacked separately when hitting the pond, and only return to the ripe soil when returning to the pond, not raw soil. after returning 30 cm of ripe soil, apply 30 kg of basic fertilizer and mix well with soil, then cover 10 cm of ripe soil, add 0.5 kg of compound fertilizer or phosphate fertilizer, and then return the soil to 20 cm above the mouth of the pond to make a tree plate, the tree plate is not less than 1 square meter. General mountain, sand flat planting, low barricade pier planting, planting sufficient base fertilizer, select strong seedlings, fine planting, base fertilizer with stable fertilizer is better, 30 kilograms per pond, add phosphate fertilizer or compound fertilizer 0.25 kilograms, mix back to the pond, do not come into direct contact with fine roots, so as not to burn roots. Before planting the seedlings, cut off the young leaves and twigs, and remove some of the overdense old branches and leaves. Even if planted in rainy days, it is necessary to irrigate enough fixed root water to keep the soil moist, and the seedlings should be untied in time after 2-3 months of survival. two。 Planting precautions do not plant citrus fruit trees within 500 meters of lemon orchard, in order to prevent flowers, produce strange fruit and reduce the quality of lemon. Promote orchard beekeeping to help improve fruit setting rate. It is firmly forbidden to interplant lemons in high-stem crops, let alone in lemon-growing areas. It is recommended to interplant some dwarf crops (preferably soybeans and peanuts) in the lemon planting land, but not vine crops. Interplanting crops should be rotated.
