Embodiment 1

[0044] Embodiment 1 The inventive method

[0045] Implementation location: dry-hot valley of Jinsha River. The dry-hot valley of Jinsha River is located at 25.5°~28.0°N, 100.3°~103.60°E, and belongs to the south subtropical climate. The annual average temperature is 20℃~23℃, the annual precipitation is 600~800mm, the annual evaporation is 2500~3800mm, and the annual evaporation is 3~6 times of the annual precipitation. The dry season is concentrated from October to June of the next year.

[0046] In this example, alfalfa WL525HQ and extra-high ryegrass were planted between the rows in the jujube orchard. Specific steps are as follows:

[0047] (1) Variety selection

[0048] The selected variety of jujube tree is Tainan No. 1 jujube tree, and the high-quality forage grass is annual extra-high ryegrass and perennial alfalfa WL525HQ.

[0049] (2) Selection and leveling of planting areas

[0050] ①Choice of planting area The dry-hot valley of the Jinsha River in Yuanmou County...

Embodiment 2

[0076] Example 2 Interplanting extra-high ryegrass and jujube

[0077] Embodiment 2 adopts a kind of forage grass of extra-high ryegrass to interplant with jujube tree, except that the following steps are different from embodiment 1, and all the other steps are the same as embodiment 1.

[0078] (1) Variety selection

[0079] The selected variety of jujube tree is Tainan No. 1 jujube tree, and the high-quality forage grass is annual extra-high ryegrass.

[0080] (3) Green jujube tree planting and sowing of high-quality forage grass

[0081] ② Sowing of high-quality forage grass

[0082] Before sowing the high-quality forage extra-high ryegrass, soak the extra-high ryegrass with 1% lime water for 10 minutes. In September when green jujube trees were planted, in the area of ​​sowing high-quality forage grass described in embodiment 1 step (2) 2. in the row sowing extra-high ryegrass between the rows of green jujube trees, cover soil 1~1.5cm after the drill sowing, especially ...

Embodiment 3

[0095] Example 3 Interplanting of alfalfa WL525HQ and jujube

[0096] Embodiment 3 uses a kind of forage grass of alfalfa WL525HQ to interplant with jujube tree. Except that the following steps are different from that of embodiment 1, the rest of the steps are the same as in embodiment 1.

[0097] (1) Variety selection

[0098] The selected variety of jujube tree is Tainan No. 1 jujube tree, and the high-quality forage grass is perennial alfalfa WL525HQ;

[0099] (3) Green jujube tree planting and sowing of high-quality forage grass

[0100] ② Sowing of high-quality forage grass

[0101] Before sowing the high-quality forage alfalfa WL525HQ, the alfalfa WL525HQ was soaked in 1% lime water for 10 minutes. In September of the same year when jujube trees were planted, alfalfa WL525HQ was drilled in the area of ​​sowing high-quality forage grass described in embodiment 1 step (2) ②, and the cover soil was 1 to 1.5 cm after the drill, and the area of ​​alfalfa WL525HQ seeding ra...

Abstract

The invention discloses a cultivation method of interplanting of two high-quality forage grasses and Zizyphus mauritiana Lam. The method comprises the steps of variety selection, selection and leveling of a planting area, planting of the Zizyphus mauritiana Lam and seeding of the forage grasses, field management and harvest and utilization of the high-quality forage grasses. The two high-quality forage grasses are annual super-high Lolium multiflorum L. and perennial Medicago sativa L.WL525HQ. The two high-quality forage grasses are subjected to row planting between the rows of the Zizyphus mauritiana Lam at the same time, the total output of dry grass is increased by 618.71 kg / mu more than the output of the interplanting of single Lolium multiflorum L. and the Zizyphus mauritiana Lam, and increased by 60.47 kg / mu more than the output of the interplanting of single Medicago sativa L. and the Zizyphus mauritiana Lam, and the average increased output values are 1546.78 Yuan / mu and 151.18 Yuan / mu respectively. Meanwhile, the labor cost for weeding is averagely reduced by 460 Yuan / mu. The method is beneficial to construction of large-area orchard grass-planted farming production bases in the Jinsha River dry-hot valley and other areas, and the new and efficient technical method is provided for the development of fruit and animal product industries in the Jinsha River dry-hot valley and other areas.

Description

technical field [0001] The invention relates to a cultivation method for interplanting high-quality forage grass and jujube trees, belonging to the technical field of agricultural and forestry production. Background technique [0002] Annual ryegrass (Lolium multiflorum L.) likes warm and humid climates, and grows fastest when the temperature is 12-27°C. It grows faster than other grasses in autumn and spring, and is most suitable for growing in areas with precipitation of 500-1500mm. It is suitable for autumn planting in the dry and hot valley of the Jinsha River. It has poor drought and cold resistance, and grows well in moist, well-drained fertile soil and irrigation conditions, but it is not tolerant to severe cold and dry heat. Whereas areas with higher elevations and cooler summers can grow for two years with proper management. Annual ryegrass has a long growth period, rapid growth, early mowing time, and strong regeneration ability. Generally, it is mowed 4 to 6 tim...
