Embodiment 1

[0028] Principle and feature of the present invention are described below in conjunction with accompanying drawing and field irrigation test, and given example is only used to explain the present invention, is not intended to limit the scope of the present invention.

[0029] The following alfalfa varieties are "tourists", as shown in Table 1 and Table 2, where Q1, Q2, and Q3 in Table 1 and Table 2 are irrigation methods with uniform irrigation devices, and the irrigation quota is 2640m 3 hm -2 、3520m 3 hm -2 、4400m 3 hm -2 , CK1 and CK2 are ordinary traditional border irrigation, and a water outlet pipe is set on the field surface, and the irrigation quota is 3520m respectively. 3 hm -2 and 4400m 3 hm -2 . In terms of field management, root-breaking treatment was adopted for Q1, Q2, and Q3 treatments, while no corresponding root-breaking treatment was adopted for control CK1 and CK2.

[0030] The root-breaking treatment is manual vertical shoveling, about 15 cm away ...

Abstract

The invention relates to a border check irrigation method and specifically relates to a border-irrigation-based quota irrigation method for alfalfa in a desert region. The border-irrigation-based quota irrigation method comprises the following steps: 1) land leveling and soil fertility grade measurement; 2) border irrigation optimal field parameter, namely preparing a land in the step 1) to form atrapezoidal section with the border width being 200cm, the border length being 2500cm, the check levee bottom width being 32cm, the check levee top width being 16cm and the check levee height being 22cm; 3) alfalfa planting, namely selecting an alfalfa variety "tourist" with high yield, drought resistance, cold resistance and short growth period, carrying out strip sowing with the depth of 6-8cmin soil under the conditions that each border is divided into 10 rows, the line spacing is 20cm, the sowing depth is 2.0-2.5cm, and the sowing quantity is 1.6kg/mu, and carrying out leveling after strip sowing; and 4) quota irrigation of alfalfa, wherein land surfaces (2) at two sides of a check levee (1) in the step 2) are provided with diversion trenches (5), and the check levee is provided witha uniform irrigation device. The border-irrigation-based quota irrigation method has the beneficial effects that due to the adoption of a technical scheme that the border-irrigation uniform water irrigation device is arranged and an optimal irrigation quota is screened, the aims of saving water and increasing the yield are achieved, and the market application prospect is good.

Description

technical field [0001] The invention relates to the technical field of border irrigation methods, in particular to an alfalfa quota irrigation method based on border irrigation in desert areas. Background technique [0002] Alfalfa is a perennial leguminous forage grass. Because of its high yield, high quality and strong stress resistance, it is one of the most important economic forage grasses in the desert areas of Northwest my country. It plays an important role in soil improvement and restoration, desertification control, and soil and water conservation. significance. [0003] The planting area of ​​alfalfa in my country is wide and has a long history. The yield and quality of alfalfa have been increased and improved to a certain extent in recent years. However, in most areas, the use of water resources in the process of planting and production of alfalfa is not reasonable, resulting in irrigation water resources. The waste is serious, and the increase in yield is not sig...
