Embodiment 1

[0045] In this embodiment, saline-alkali land includes moderately saline-alkali land, and the salinity of the soil is 0.3% to 0.6%.

[0046] The size of the square field in S3 is 60m×50m.

[0047] In S4, salt pine was planted in advance and the height was set at 1.5m. Salt pine was planted in the furrows and flooded with water. After 4-6 months after the salt pine seedlings survived, the salt content in the soil decreased, and then interplanted alfalfa, Caragana.

[0048] Saline-alkali land is moderately saline-alkali land, that is, when the soil salinity is 0.3%-0.6%, the planting ratio of salt pine to alfalfa or caragana is 2:3.

[0049] The biological bacteria fermented fertilizer on S2 adopts crop stalks, wherein the crop stalks include any one or several of corn stalks, wheat straws, cotton stalks, potato straws, and rice straws, and the amount of biological fermentation fertilizer is 0.1-0.15 m 3 / m 2 ;Phosphogypsum is 2~3kg / m 2 , After fertilization, the depth of soi...

Embodiment 2

[0055] The difference from Example 1 is that the saline-alkali land in this embodiment is severe saline-alkali land, that is, when the soil salinity is above 0.6%, the planting ratio of salt pine to alfalfa or Caragana is 4:5, and 2 rows of salt pine are planted in the furrows. The row spacing is 0.5m, the row spacing of Yansong No. 1 is 1m, and the row spacing of Yansong No. 2 is 0.5m. Plant 5 rows of alfalfa or caragana on the ridge, and the row spacing is 0.5m×0.5m; The ditch is 0.3m deep, 0.75m wide at the bottom and 1m wide at the top.

[0056] It should be pointed out that the Yansong No. 1 and Yansong No. 2 used in the first and second parts of the present invention are Chinese Tamarix species developed and cultivated by Shandong Sanyi Landscaping Co., Ltd.: Yansong No. 1, Salt Inspection No. 2.

[0057] The method of interplanting salt pine with forage plants alfalfa and caragana in medium-to-severe saline-alkali land: through the measurement of soil salinity in moder...

Abstract

The invention provides a pinus sylvestris ssp.kulendensis and forage plant alfalfa and caragana korshinskii kom interplanting method in moderate-severe saline-alkali soil. The method includes the following steps that S1, sampling is performed to measure soil salinity and alkalinity of moderate-severe saline-alkali soil, and the interplanting planting ratio of pinus sylvestris ssp.kulendensis, alfalfa and caragana korshinskii kom is determined; S2, biological bacterium fermentation fertilizer is applied to implementation segment soil, phosphorus gypsum is used in cooperation, and then deep ploughing is performed; S3, moderate-severe saline-alkali soil is prepared, a ridging soil preparation mode is adopted during soil preparation, the soil is divided into a plurality of square fields, and drainage ditches are formed in the periphery of each square field in an excavation mode; S4, interplanting is performed in the mode that pinus sylvestris ssp.kulendensis is planted in advance, and then alfalfa and caragana korshinskii kom are planted in an interplanting mode; S5, maintenance management is performed on interplanting field, and alfalfa and caragana korshinskii kom are harvested regularly. The interplanting method can effectively solve a series of problems that falfa and caragana korshinskii kom forage plants cannot grow in moderate-severe saline-alkali soil, and salinity and alkalinity of moderate-severe saline-alkali soil are improved.

Description

technical field [0001] The invention belongs to the technical field of saline-alkali land improvement, in particular to a method for interplanting salt pine with forage plants alfalfa and caragana in medium-severe saline-alkali land. Background technique [0002] At present, the area of ​​saline-alkali land in my country is 100 million hm 2 , about 30 million hm of saline-alkali wasteland 2 , accounting for one-fifth of the world's saline-alkali land area. More than 1.33 million hm of saline-alkali wasteland in Shandong Province 2 . Due to the frequent occurrence of saline-alkali, hardening and barren problems on saline-alkali land, it seriously restricts the development of agriculture and forestry on saline-alkali land. The utilization of saline-alkali land resources and the improvement of salinized cultivated land are one of the important links in the development of agricultural production in areas with saline-alkali land. Forage plants alfalfa and caragana are plants...
