Problems solved by technology

[0005] In order to solve the technical problems of low survival rate of seedlings and difficulty in controlling weeds in the prior art, which consumes a lot of cost, and the large amount of pesticide application threatens the sustainable development of agriculture, the present invention provides an intercropping construction of Cryptogia amansifolia on sandy land. Planting methods can improve the survival rate of seedlings of Cryptospermia amansifolia seed field, suppress weeds, and then achieve the purpose of reducing production costs and pesticide application, and protecting the ecology of desert areas.

Embodiment 1

[0026] Example 1 Establishment of intercropping of Cryptospermia acanthus and wheat

[0027] In 2015, in Minqin County, Gansu Province, intercropping of wheat and Amansia amansica was carried out. The wheat is the local mid-late maturing variety Ningchun No. 4, and Amansia amangus is a wild grass species.

[0028] The specific planting method is as follows:

[0029] 1. Land preparation

[0030] The seeds of C. amansifolia are very small and not resistant to flooding. Before sowing, the soil should be carefully prepared, and the sand should be leveled and suppressed. Flood once.

[0031] Ammonium dihydrogen phosphate 200kg / ha was applied as base fertilizer. The base fertilizer can provide enough nutrients for the growth of wheat and Cryptospermia acanthus.

[0032] 2. Sowing

[0033] Sowing time is June 9th. Wheat is sown using traditional wheat seeders. The wheat sowing rate is 150kg / ha, the row spacing is 10cm, the sowing depth is 3-4cm, and every two seeders are re...

Embodiment 2

[0039] Example 2 Intercropping of Cryptodica amansifolia and oats

[0040] In 2015, in Minqin County, Gansu Province, intercropping of oats and Amansia awnicae was carried out. The oat is Qingyin No. 1, and Yinzicao is a wild grass species.

[0041] Concrete planting mode is identical with embodiment 1.

[0042] The specific planting effect is as follows: Compared with the single-sowing Cryptospermia awnsica under the same management conditions, the seedling survival rate of the field treated with intercropping of oats and Cryptospermia awnsica seeds increased by 18 percentage points, and all experimental fields were successfully planted. The weed cover is reduced by 79%, and the weed biomass is reduced by 76% ( figure 1 ), exempting 2 manual weed control operations, greatly reducing costs.

[0043] Evaluation of the effect: the survival rate of the seedlings of C. amansifolia significantly increased, and the weed control effect was good.

Embodiment 3

[0044] Example 3 Establishment of Intercropping of Cryptospermia awnicae and Wheat

[0045] In 2015, in Minqin County, Gansu Province, intercropping of wheat and Amansia amansica was carried out. Wheat is a middle-late maturing variety Ganchun No. 25, and Yinzi Grass is a wild grass species.

[0046] The specific planting method is as follows:

[0047] 1. Land preparation

[0048] The seeds of C. amansifolia are very small and not resistant to flooding. Before sowing, the soil should be carefully prepared, and the sand should be leveled and suppressed. Flood once.

[0049] Ammonium dihydrogen phosphate 210kg / ha was applied as base fertilizer. The base fertilizer can provide enough nutrients for the growth of wheat and Cryptospermia acanthus.

[0050] 2. Sowing

[0051] Sowing time is June 7th. Wheat is sown using traditional wheat seeders. The wheat seeding rate is 160kg / ha, the row spacing is 10cm, the sowing depth is 3-4cm, and every two seeders are removed. The r...

Abstract

The invention provides a planting method for cleistengenes songorica intercropping on sand. According to the method, annual plants with large seeds, thicker stems, a large number of leaves and high growing speed are used for intercropping with cleistengenes songorica. By the application of the intercropping method, the survival rate of cleistengenes songorica seedlings can be increased by 17% or above, the weed cover degree is reduced by 77% or above, the production cost and the pesticide application amount are reduced greatly, and the ecological environment of desert regions is well protected.

Description

technical field [0001] The invention relates to a method for intercropping and planting cryptogonia amansifolia on sandy land. Background technique [0002] Amansia awnica is an important perennial gramineous plant in the desert steppe of Northwest China. It can grow in areas with an annual rainfall of 120 mm. It has the characteristics of drought resistance, cold resistance, barren resistance, and extensive management tolerance. Under drought conditions, the turf quality score of C. awnicae can reach 7.1, which is significantly higher than that of fescue reediformis. At the same time, the grass species grows slowly, which can reduce the number of times of lawn mowing and reduce the cost of lawn maintenance and management. This grass seed has great ecological application value and turf industrialization prospect in the arid, semi-arid and arid desert regions of Northwest my country, and the demand for seeds is increasing year by year. [0003] The biggest difficulty in the...
