Technical points of new citrus orchard

First, the construction of the park should be of high quality and start early. The key point is to draw a good trench and apply sufficient bottom fertilizer, do a good job in the first pass of the construction of the garden, draw a trough with a width of 1 meter and a depth of 0.6 meters according to equal height, fill 2500 Mele 30000 kilograms of green manure per mu, and apply appropriate amount of nitrogen and phosphorus fertilizer; secondly, low-lying land and paddy fields should open drainage ditches, and the main drainage ditch is more than 0.80 meters deep, in order to reduce field humidity and reduce diseases and insect pests. The time of establishment of the garden should be started in time after autumn harvest to ensure that green manure and soil have enough time to rot; field seedlings had better be planted before late October (mid-March in spring), and container seedlings should be planted before October (after March in spring). Planting time should be early rather than late.

Second, the distance of seedling transportation should be close, and the quality should be excellent. The seedlings have the advantages of long transportation distance, long transportation time, large root damage and low survival rate; secondly, the purity of varieties can not be guaranteed and the risk of quarantine venereal diseases and insect pests is high. It is suggested that all villages organize villagers to purchase seedlings within the scope of this area, and it is strictly forbidden to purchase seedlings in epidemic areas. if they really need to buy seedlings from other places, they should also purchase them nearby, and the "three certificates" of seedlings are complete; the stacking level of seedlings should not be too high and the roots should not be too crowded during transportation. to prevent root burning and affect the survival rate of planting.

Third, management should be diligent after planting. The task within half a year after planting is to ensure survival, with emphasis on water management, and the need to maintain appropriate soil moisture, of which the first month after planting is the most important. In order to ensure survival, it is suggested that the root system should be mudded at seedling time and planted in the field in time. The first watering should be thoroughly after planting, and the tree plate should be covered with grass after planting. After that, the watering time should be watered every 5 seconds every 7 days, and the watering interval can be appropriately extended after one month. However, it is necessary to maintain the suitable soil moisture for root growth. After the spring shoot matured in the first year, the fertilizer was applied once a month, so that the thin fertilizer was applied frequently. The main type of fertilizer was ternary compound fertilizer, which was applied in shallow ditch, and the amount of fertilizer increased gradually from less to more. Prune trees as little as possible, leave more branches and leaves, and do a good job in prevention and control according to the occurrence of diseases and insect pests.
