I. Pre-planting work
1. Planting principles: The plan is to plant dense plants. After entering high-yield crops, they will be gradually transplanted or eliminated weak plants. It is advisable to plant 148 or 111 plants per acre.
2, planting time: every year from October to the end of March the following year can be planted. Among them, the best period for planting in October is because the temperature at this time is suitable for fruit trees to resist winter and spring drought.
3. Before planting: According to the spacing of 3 m 1.5 m or 3 m 2 m, turn the set point 80 cm wide, or loosen the whole field, the depth is appropriate to see raw soil, and then dig 30 cm square, 5 cm deep planting hole. Straighten and dip into the plant to facilitate future management. However, attention should be paid to not digging the trenches, deep holes or backfilling after cultivation. Because the raw soil directly contacts the seedlings, the root growth of the seedlings is not good.
4. Garden choice: The garden is suitable for sand and loam. The specific requirements are: the terrain is high dry, sunny, leeward, deep soil, fertile soil, loose air, low groundwater level, previously not planted peach, plum, apricot or plant more than 5 years after the interval, and convenient transportation.
Second, seedling planting
1. Planting techniques: Moderately short, dense planting, the advantages are: 1 effective in advance, early entry into high-yield stage. Because of the crispy red plums and crisp young Lishu trees, it is easy to form flower buds. After management, they can see results. However, due to the slow growth of tree saplings after fruiting, if the density is increased moderately, the fruit can be promoted. 2 is conducive to plastic surgery, trimming, spraying, fruit thinning and fruit picking. (3) Short trunks are conducive to tree nutrient delivery, which will help to produce high-quality fruit. 4 The short tree and branch density can weaken the wind and enhance the wind resistance of the tree.
2, planting methods: 1 to promote fibrous root development, the root slightly cut off the seedlings, with carbendazim plus rooting agent, the root immersion sterilization before planting. 2 seedlings should not be planted too deep, generally kept in the yin and yang of the seedlings. When the roots are planted, the roots are spread out, and the fine soil is filled with the seedlings. After the seedlings are established, the piers are stepped onto the piers. The piers must be raised 20 to 30 cm above the ground to form a hoe shape. (If you plant too deep, the seedlings will grow slowly, because the root system must also breathe and heat). 3 After planting, only white water can be used as a root-setting water, because the fertilizer can easily infect the roots. After seeing the seedlings, the topsoil will be dried and then watered. 4 before planting leaves, seedlings can not cut or slightly cut. If the seedlings are slightly cut or not cut, only the top leaf buds will be forced after the planting, and the leaf buds will be forcibly stressed when sheared. However, after the germination, the leaf buds will not be able to withstand frost, and there will be no leaf buds in the early spring, which will easily lead to the death of the seedlings. Before the leaves fall to the seedlings, all the leaves of the seedlings must be removed to prevent the leaves from depleting the seedlings and affect the survival rate.
Third, the new plant management and intercropping
After the spring, the seedling soil is tapped and weighed up to 80 cm, then watered, covered with moisturizer, and warmed, and the weeds in the tree tray are removed at any time. Lishu trees should not be planted with high stem crops. Dwarf crops cannot be planted too close, so as not to affect Li Miao photosynthesis and soil heating. The interplanting is generally based on dwarf vegetables and medicinal materials with high economic benefits, which have both short-term economic benefits and fertilized soil.
