Embodiment 1
[0024] From 2009 to 2010, the heavy saline-alkali land of Konka Company in Karamay Agricultural Development Zone, application demonstration of 150 mu, set up 4 experimental plots, with an area of 225m2 2 (15m×15m);
[0025] land selection, land preparation
[0026] The test site selects heavy saline-alkali land with a salt content of 3.0% in the 0-30cm soil layer, cultivates Suaeda salsa in saline land, and plows and harrows before planting to make the surface soil smooth and finely divided;
[0027] Drip irrigation belt layout
[0028] The capillary drip irrigation belt is laid out in the way of "one pipe and one row", the distance between the drip irrigation capillaries is 0.6m, and the flow rate of the drip irrigation emitter is controlled at 1L / h;
[0029] sowing
[0030] The sowing period is selected from late April to early May. The planting method is drill sowing. Mix the seeds of Suaeda salsa with fine sand and water until they are scattered, and plant them on bot...
Embodiment 2
[0034] In 2011, in the heavy saline-alkali land of Xiaoguai Township, Karamay, the application demonstration area was 100 mu, and 4 experimental plots were set up, with an area of 225m 2 (15m×15m);
[0035] land selection, land preparation
[0036] The test site selects a heavy saline-alkali land with a salt content of 5.5% in the 0-30cm soil layer, cultivates Salicornia, and plows and harrows before planting to make the surface soil smooth and finely divided;
[0037] b. Drip irrigation belt layout
[0038] The capillary drip irrigation belt is laid out in the way of "one pipe and one row", the distance between the drip irrigation capillaries is 0.8m, and the flow rate of the drip irrigation emitter is controlled at 1.5L / h;
[0039] c. Sowing
[0040] The sowing period is selected from late April to early May. The planting method is drill sowing. Mix the seeds of Salicornia salicornia with fine sand and water until they are scattered, and plant them in the areas on both ...
Embodiment 3
[0044] In 2011, in the heavy saline-alkali land of Xiaoguai Township, Karamay, the application demonstration area was 100 mu, and 4 experimental plots were set up, with an area of 225m 2 (15m×15m);
[0045] land selection, land preparation
[0046] The test site selects heavy saline-alkali land with a salt content of 4.0% in the 0-30cm soil layer, cultivates Suaeda salsa, and plows and harrows before sowing to make the surface soil smooth and finely divided;
[0047] b. Drip irrigation belt layout
[0048] The capillary drip irrigation belt is laid out in the way of "one pipe and one row", the distance between the drip irrigation capillaries is 1.0m, and the flow rate of the drip irrigation emitter is controlled at 2L / h;
[0049] c. Sowing
[0050] The sowing period is selected from late April to early May. The planting method is drill sowing. Mix the seeds of Suaeda salsa with fine sand and water to loose grains, and plant them in the areas on both sides of the capillary...
