1. The establishment of a tea park: the choice is to build a park along the sandy sandy land, which is so rich in water and water. 2. Selection of healthy trees: the choice to grow with well-developed roots, strong growth and one-year-old seedlings. 3. Peak improvement and fertility: the key measures to improve the conditions on the ground are the basis for early fruit, quality and productivity. 4 fertilization methods: use of circular ditches. 5. Rational detour, packs: stunted deformation, small fruit and insect fruit, and at some point bagage。
I. Equipment
It has been chosen to build a park in the middle of the sandy sandy land, which is three metres in length and three metres in length, in the middle of which it is better to plant a triangle. Three red grapefruits can be grown every four seasons of the year, after they have matured。
Ii. Choosing strong trees
Growing with well-established, healthy, one-year-old seedlings is chosen and, with better management conditions, the trees will soon be able to recover growth and canopy formation。
Iii. Place reform and employment
1. Important measures to improve land conditions are the basis for early fruit, quality and productive production. Peak conversions generally begin the second year after cultivation and are best achieved in the third year。
Under the canopy drip line, a ditch of 60 to 70 centimetres deep and 40 to 50 centimetres wide is dug symmetrically on both sides, filled with green fat, burning soil, 1. 5 kg of phosphorus fertilizer, appropriate amounts of lime and topsoil, and applied in layers to pressure soil improvement。
Iv. Reasonable trim, correct stripping
1. The principle of cutting: the use of twigs, multiple cuttings of the outer edges of the canopy and a small cut of the inner chamber branches。
2. Cutting time: teenage grapefruit tends to be trimmed twice, i. E. Summer and winter, and the result is typically trimmed three times, i. E. Spring, summer and winter. Spring cut in february-march, summer cut in may-july and winter cut in the second half of the fruit harvest, october-november。
3 shearing methods: rather than a one-size-fits-all approach, emphasis is placed on removing branches from the outer edges, and on the dense canopy canopy can be trimmed with open windows. This method effectively controls tree crowns, promotes the growth of inner-breeding branches and does not lead to a reduction in production as a result of re-cutting. The inside branch is cut off from the result branch, the dead branch, the sick branch and the weak branch. In late september, euphoria trees, which do not bloom or are less flowered, were stripped。
V. Fertilization methods
The frequency of fertilisation is applied in circular ditches, in accordance with the requirements of the gestation, incubation and fertilisation, which are applied three to four times a year。
Vi. Equitive shoots, skits
Developmental malformations, small fruit and insect fruit are first to be removed, with the result generally being foliage ratio (160-200):1 better. When the fruit is diarrhea, the bag shall be made from 100 to 150 grams of single fruit and 5 centimetres across the fruit. The bag should be kept wide and moderate, so that neither the mouth of the bag can be unsealed nor the fruit handles may be damaged。
