[0004] Currently, suitable green manures are artificially planted in saline-alkali land, such as succulents and sage, which are mostly annual or perennial green manures. The following problems exist in natural grass and artificial grass in saline-alkali land: 1. The surface is exposed in the early stage of growth, which is easy to cause the problem of salt return 2. Natural grass growth in saline-alkali land will cause malignant weeds to grow wildly, and the cost of artificial weeding is high; 3. When the life cycle of green manure is completed, bare land will be formed. On the one hand, weeds will grow, and on the other hand, the salt in the bare land will precipitate
Climbing orchid is suitable for growth. It can grow on heavy clay soil to sandy soil at a pH value of 5-7. During the vigorous growth period, it can form a thick layer of more than ten centimeters of grass cushion, but its salt tolerance is relatively low. Difference
At present, the orchids in Fujian Province are mostly interplanted with tea gardens on hillsides, and there are no relevant reports on the interplanting of orchids in coastal saline-alkali lands.

Embodiment 1
[0025] A method for interplanting dragon fruit in coastal saline-alkali land with creeping orchid, comprising the following methods:
[0026] 1) Fruit trees are planted in wide rows and densely: the salt content of the coastal saline-alkali land is about 1.8‰, and the red dragon fruit is planted in rows. Remove the weeds in the whole garden before planting, dig a ridge height of 30cm, dig a shallow ditch 20cm deep and 20cm wide, use iron pipe columns as support, and transplant seedlings in the first ten days of March, plant 2 plants per column, column spacing 0.6m, row spacing 2.5m, plant about 850 plants per mu;
[0027] 2) Cutting orchid orchid cuttings: in mid-March, select robust and pest-free branches of orchid orchid, cut the middle twigs into 10cm sections, leave 2 buds, and dig 15cm deep between rows about 60cm away from the iron pipe column. A planting hole with a width of 15cm, that is, interplant 2 rows of creeping orchids between rows of fruit trees, apply organic...
Embodiment 2
[0030] A method for guava interplanting creeperia in coastal saline-alkali land, comprising the following methods:
[0031] 1) Wide row planting of fruit trees: The salt content of coastal saline-alkali land is about 2.7‰. Weeds in the whole garden should be cleared before planting. Ruby guava was planted in early March and grafted with 3-year-old seedlings, with a plant spacing of 2.5m and a row spacing of 3.5m. strain. After transplanting, dig a drainage ditch 50cm deep and 30cm wide in the middle of each row, which can have a good drainage and salt discharge effect;
[0032] 2) Transplant Climbing Orchid: Transplant the seedlings cultivated in the greenhouse in November of last year in the first ten days of April, dig a planting hole 15 cm deep and 15 cm wide between rows about 80 cm away from the fruit seedlings, apply organic matter ≥ 60%, N+P2O5+K2O ≥ 5% commercial organic fertilizer and 500g of mountain red soil mixed with the same weight, transplanted 2 creeping orchi...

Abstract
The invention provides a method for interplanting creeper orchids with fruit trees in coastal saline-alkali land, comprising the following steps: (1) planting fruit trees in wide rows; (2) planting creeper orchids; (3) laying weed-proof cloth. In the present invention, the weed-proof cloth and the orchard grass are used in combination, and the weed-proof cloth can be used to control the growth of weeds in the early stage of climbing orchid planting, and reduce the impact of the exposed salt on the saline-alkali ground surface on young fruit trees when the grass is not fully covered. Injury, and the impact on the growth of creeper orchid, greatly save the labor of weeding. The invention is particularly suitable for planting fruit trees in light-to-moderate (salt content 1‰-4‰) coastal saline-alkali land.
Description
technical field [0001] The invention relates to a technique for planting fruit trees in coastal saline-alkali land, and in particular to a method for interplanting cremegrass in coastal saline-alkali land. Background technique [0002] In recent years, in order to improve the comprehensive benefits of saline-alkali land, some coastal saline-alkali wastelands in coastal areas of Fujian Province have begun to cultivate fruit trees, such as dragon fruit, guava, passion fruit, grapes, figs, etc. The coastal light and heat conditions are sufficient, mildly saline-alkali land (salt content 1‰-2‰) is overgrown with weeds, and the cost of manual weeding is high. The application of herbicides will aggravate the deterioration of soil quality in saline-alkali land. For this reason, the use of weed-proof cloth in the cultivation of fruit trees in saline-alkali land is a major trend in recent years. [0003] For moderate saline-alkali land (salt content 2‰-4‰), the exposed salt on the s...
