Embodiment Construction

[0026] The present invention is applied to the planting method of improving saline-alkali land soil to establish a poplar forest field. The advanced seedling-raising cup seedling cultivation method can be used to cultivate healthy and disease-free poplar saplings, and the saline-alkali land planting is carried out by transplanting, and the poplar saplings are drip-irrigated. Apply poplar-specific organic liquid fertilizer and poplar-specific solid organic fertilizer at intervals to lay a good foundation for the growth of poplar, improve the structure of saline-alkali land through the growth of poplar, reduce the content of salinity and form an environment suitable for biological growth.

[0027] The process is roughly divided into the formulation of seedling cups, organic fertilizer and guest soil treatment, seedling selection, cuttings, and transplanting management.

[0028] Special seedling cups are used for seedling raising and transplanting, such as figure 1 As shown, the ...

Abstract

The invention discloses a culturing and planting method of poplar trees for improving saline and alkaline land. The culturing and planting method comprises the steps of culturing seedlings and transplanting, wherein the step of culturing the seedlings comprises the following specific steps of: filling a seedling culturing cup with compost, screening dormant wood of poplar tree seeds and cutting the dormant wood into the seedling culturing cup and culturing in a greenhouse for 50-70 days until tree seedlings survive; the step of transplanting comprises the following specific steps of: digging a pit which can be used for accommodating the seedling culturing cup on the transplanting land, wherein the depth of the pit is greater than the height of the seedling culturing cup; filling organic fertilizer special for the poplar trees in the pit; removing the bottom of the seedling culturing cup for accommodating the survival tree seedlings, placing the seedling culturing cup into the pit and tamping with soil; and irrigating and fertilizing by adopting a drip irrigation system. By using the method, a method for culturing the seedlings in a paper cup, which is suitable for the poplar tree seedlings, is designed according to growth characteristics of the poplar trees, so that the dormant period is shortened, the poplar trees enter the growth period 1-2 years ahead and the survival rate of the poplar trees reaches over 95 percent. Meanwhile, according to the method, diseases of the poplar trees can be effectively prevented, the incidence rate of bacterial diseases is reduced by over 30 percent, cross infection in the seedling culturing process can be avoided and the control rate over the disease reaches over 95 percent.

Description

[0001] technical field [0002] The invention relates to a poplar breeding method, which is mainly applied to the large-scale planting and cultivation of poplar buds, which can promote the growth and development of poplars and improve the soil ecological environment of saline-alkali land, so as to control and reduce salinization. Background technique [0003] The current traditional poplar planting method is: use poplar branches that have been dormant for 1 to 2 years in the nursery in spring for dense cuttings, and after 1 to 2 years, transplant when the seedlings grow to about 2 meters high; The poplar saplings just enter the normal growth period after two years. The annual transplanting time is very short, usually from late April to mid-May. [0004] According to the above-mentioned traditional planting method, poplar saplings need at least 2 years and at most 4 years to enter the growth period, and the survival rate is below 50%. [0005] The traditional method of...
