Embodiment 1

[0026] Embodiment 1 Application of a saline-alkali land brackish water and fresh water rotation irrigation method in the planting of cypress pine herbs

[0027] Step 1, raising seedlings

[0028] Before sowing, put the seeds in the sun for 2-3 hours, then soak the seeds in warm water at 25-30°C for 12 hours, after drying, mix them evenly with moist fine sand, place them in a room at 20-25°C for 3-4 days, and wait until the seeds are mostly Sow after dew. Select a good plot as a seedbed, densely sow seedlings, the distance between rows and plants is 5cm×5cm, the sowing depth is 1.5cm, cover with a layer of burnt marl and fine soil, and then cover with straw, spray water frequently to keep it moist. After the seedlings have emerged, remove the cover. Water frequently to keep the seedlings in water.

[0029] When the seedlings grow to 3-4 true leaves, they are ready to be transplanted.

[0030] Step 2. Prepare the planting area

[0031] The planting area is saline-alkali lan...

Embodiment 2

[0061] Embodiment 2 Application of a saline-alkali land brackish water and fresh water rotation irrigation method in the planting of cypress pine herbs

[0062] Adopt the planting method of embodiment 1, only change step 4 irrigation, carry out embodiment 2 and plant cypress herb.

[0063] The irrigation steps of embodiment 2 are as follows:

[0064] (1) Seedling irrigation

[0065] Irrigate using brackish water and fresh water rotation irrigation, the ratio of brackish water and fresh water rotation irrigation is 1:5, irrigate once every 6 days, and the amount of irrigation each time is 330m3 / ha; the salinity of the fresh water is less than 1g / L, the salinity of the brackish water is 2.6g / L, the pH is 8.0, the salt content is 0.11%, and the sodium salt content accounts for 72% of the total salt content.

[0066] (2) Irrigation during the growth period

[0067] Irrigate with salt water rich in organic matter and fresh water in rotation, the frequency ratio of salt water r...

Embodiment 3

[0078] Embodiment 3 A kind of brackish water and fresh water rotation irrigation method in saline-alkali land and its application in the plantation of cypress pine and herb

[0079] Adopt the planting method of embodiment 1, only change step 4 irrigation, carry out embodiment 3 and plant cypress herb.

[0080] The irrigation steps of embodiment 3 are as follows:

[0081] (1) Seedling irrigation

[0082] Irrigate using brackish water and fresh water rotation irrigation, the ratio of brackish water and fresh water rotation irrigation is 1:5, irrigate once every 6 days, and the amount of irrigation each time is 360m3 / ha; the salinity of the fresh water is less than 1g / L, the salinity of the brackish water is 2.8g / L, the pH is 8.2, the salt content is 0.12%, and the sodium salt content accounts for 75% of the total salt content.

[0083] (2) Irrigation during the growth period

[0084] Irrigate with salt water rich in organic matter and fresh water in turns, the ratio of sal...

Abstract

The invention provides an organic matter-enriched brackish water irrigation method for saline-alkali soil and application of the irrigation method in planting of silphium perfoliatum. The irrigation method comprises seedling-stage irrigation, wherein irrigation is carried out in the ratio of times of rotation irrigation of the brackish water to fresh water is 1:5, and the amount of irrigation at each time is 300 to 360m<3>/hectare. The irrigation method also comprises growing-stage irrigation, wherein irrigation is carried out in the ratio of times of rotation irrigation of organic matter-enriched saline water to the fresh water is 1:2, the amount of irrigation at each time is 450 to 500m<3>/hectare, and the organic matter-enriched saline water is formed by dissolving an organic matter-enriched fertilizer into the brackish water and performing uniform mixing. The irrigation method further comprises cutting-stage irrigation, wherein irrigation is carried out in the ratio of times of rotation irrigation of the saline water to the fresh water is 1:3, and the amount of irrigation at each time is 500 to 560m<3>/hectare. According to the irrigation method, the annual output of fresh grass for planting of the silphium perfoliatum is 12.8 to 13.2 tons/acre, and the planting survival rate is 99.5 to 99.8 percent.

Description

technical field [0001] The invention belongs to the field of agriculture, and relates to a brackish water irrigation method, in particular to a brackish water and fresh water rotation irrigation method in saline-alkali land and its application in the planting of pine and herb. Background technique [0002] At present, salt water irrigation technology mainly includes individual irrigation and mixed irrigation. The key technology of mixed irrigation lies in the proportion of mixed irrigation and the selection of salt water. In addition, the amount of irrigation is also an important aspect. In the case of water resources permitting, the use of mixed irrigation not only makes full use of the water resources of the saline-alkali land, but also can improve the soil of the saline-alkali land. [0003] But the brackish water irrigation technique of the prior art has the following defects: adopt the irrigation method of the prior art, and the annual yield of the fresh grass of plant...
