What are the main technical measures for the early production of dates? (1) selection of varieties according to local conditions: the choice of varieties, in addition to abundance and quality, takes into account land conditions or regionalization practices. The deep, fertile and clayy areas of the earth are developed on golden date, non-nuclear date, sandy soil for the planting of round date, date-palm, date-palm, date-palm, date-palm, etc. It is desirable for the fertile mountains to plant strong and strong red dateage. (2) selection of saplings: long, fast-growing, fast-growing, early production. The criteria for seedlings are: thick and thick, about 1. 5 metres high, more than 2 cm diameter in the root, about 1 cm diameter in the secondary branch of the central branch, with well-developed roots, with a 30 cm long mare and many fine roots. (3) cultivation density: cultivation density shall be considered according to the method of production, the condition of the land and the characteristics of the species. It is possible to build a pure home or to use date and grain. Strongly growing varieties (e. G., red-trees, bell-trees) range from 4 to 5 metres in length and 6 to 7 metres in line, and weak varieties (e. G., golden-skin dates) range from 3 to 4 metres in length and 5 to 7 metres in length. The flat dates and grains range from 3 to 4 metres and 15 to 20 metres. Mountain areas can grow on the outer edge of the terraces, from 4 to 5 metres. In order to increase early yields, planned plantings can also be introduced, such as the construction of a primary plant road of 2 x 3 metres, with a subsequent shift of 4 x 6 metres. (4) plantation techniques: autumn planting or spring planting may occur before or after the fall of leaves and spring planting may take place in the bud. Before planting, every effort is made to dig a large den to grow with a ligen system, where organic fertilizer is applied and the leaves, weeds and earth are mixed, care should be taken to follow the seedlings, which should be slurled to prevent water loss. The plant is filled with water in a timely manner and the trees cover the membranes in order to provide protection. (5) enhanced management of fertilizing water: while date-trees are easy to produce, early yields are low, mainly due to management of gratuity, lack of fertilizers, and slow growth of larvae, thus enhancing soil management and increasing the application of fertilizing water, and promoting rapid growth of larvae are key to early production. The date-palm planting should be followed by a deep-dimensioned soil per year, which should be completed in three to four years. It is applied early in the autumn, less than once every year. It is applied long-term, mainly before the gust and at the speed of the baby's fruit. It is repeated in the flowering and fruit expansion periods. Water is pumped mainly in april-june. (6) orthopaedic shears: trees should be formed in the form of a main stem stubble of 7 to 9 branches, with 3 floors, 3 to 4 floors, 2 to 3 floors, 1 to 2 floors, and 2 to 3 branches on the main branch. Natural happiness can also be used for dry or weaker varieties. Since trees have branches and flowers, the main purpose of larvae trims is to build a rational tree structure, rapidly expand the canopy, cultivate the group of trees with good results, and lay the foundation for productive growth. The dry height park is 1 to 1. 2 metres and 1. 5 metres between. After drying, the second branch of the tectonic belt is removed, and if the second branch is strong, a short section can be left to stimulate the emergence of new dates for intermediate extension branches or main branches. In the following years, short stem branches are extended during the winter cut, and the second branch of the branch requiring hair is removed or cut short, the date of the hair is stimulated, the side branches or branches are raised, and the length of the head is increased or the tree canopy has been consummated, so that five to six years can complete the cultivation of the branch. The development of branches of the result can also take the summer-crystal approach, which is sufficient when the branches of the culture reach their intended length. There should be as many branches as possible, or temporary branches, in order to increase the number of luminous areas to support trees and increase early yields. (7) increase in sit-in rates: in early childhood, where nutrition tends to grow more difficult to sit on, the heart-picking of date-palms during the bouquet can make full use of the increase in the number of outcomes on the dates. When young trees reach a certain age, they can be stripped of their main stem (strength), usually with a dry diameter of 7 to 8 cm or more, with a density of 3 to 4 cm; for varieties such as golden date, which is heavier than the flower, it is good to be stripped at the beginning of the flowering season; and for species such as cylindrical date, which is heavier than the fruit, it is better to be stripped at the peak of the fall. In addition, the spraying of 10-15 ppm of cactin at the beginning of the flower can significantly increase sitting rates and the production of dates。
