experiment example 1

[0025] Experimental example 1 was planted under different fertilizers, bacterial fertilizers and plant hormones

[0026] Planted in the grassland desertification zone of Tangke Town, Ruoergai County, adopt 7 factors and 3 levels of orthogonal design in the desertification zone, choose flat desertification land in the desertification zone of Tangke Town, the area of ​​the plot is 1m×1m, each treatment is repeated three times, and untreated See Table 1 for the sample quadrat as a control. Apply fertilizers (AF1, AF2), plant plants after BF treatment, and apply hormones (PP333, GA 3 , ETH, CCC) processing, photographed on August 20, 2019.

[0027] Plant seeds include: old awn wheat (Elymus sibiricusLinn.), Elymus dahuricusTurcz., oats (Avena sativaL.). Fertilizer: sandy type Attapulgite fertilizer (Attapulgite fertilizer 1, AF1), saline type Attapulgite fertilizer (Attapulgite fertilizer 2, AF2). The sandy type concave-convex fertilizer comprises the following components in pa...

experiment example 2

[0031] Experimental example 2 Grassland plant coverage image collection and result analysis

[0032] Use the Huawei mobile phone P10 to collect information, and shoot the experimental quadrat from directly above. Process the collected images, correct and remove background interference: use Photoshop software to preprocess the pictures, and correct the pictures by adjusting the vertical perspective, horizontal perspective and geometric distortion, so that the quadrats appear rectangular, which is convenient for subsequent processing. Since the sample quadrat contains black and brown color blocks, which will affect the data results during normal processing, the background processing is performed through the color block replacement function, and the black and brown color blocks are replaced with white to reduce interference.

[0033] Use Image J software to process the picture into black and white mode, enhance the contrast between the background and the measurement object, adjus...

Abstract

The invention discloses a composition for plant growth in sandy soil and its application. The composition comprises: sandy type concave-convex fertilizer, saline-alkali type concave-convex fertilizer, chlormequat, ethephon and gibberellin; wherein, sandy type concave-convex fertilizer The mass ratio of fertilizer and saline-alkali type concave-convex fertilizer is 2:1; the sandy type concave-convex fertilizer contains the following components in parts by weight: 50% organic fertilizer, 20% humic acid, 5% phosphate rock and 25% organic matter; saline-alkali The type concave-convex fertilizer comprises the following components in parts by weight: 43% organic fertilizer, 12% humic acid, 5% phosphate rock and 40% organic matter, and the pH adjustment is 6.5; the quality of chlormequat, ethephon and gibberellin The ratio is 2:1:3. The composition for the growth of plants in sandy soil of the present invention, through the combination of sandy type uneven fertilizer, uneven fertilizer base, auxin, gibberellin and chlormequat and a reasonable ratio, the synergistic effect of each component , can well improve the plant coverage of land desertification, and achieve the purpose of restoring the environment.

Description

technical field [0001] The invention relates to a composition for plant growth in sandy soil, in particular to a composition for plant growth in sandy soil and application thereof. Background technique [0002] In recent years, the global desertification area has gradually increased, and the situation of soil desertification in China is severe. According to the results of the fifth national desertification and desertification monitoring in 2014, the total area of ​​desertified land in the country is 172.1175 million hm 2 , accounting for 17.93% of the total land area. The causes of sandy soil include wind erosion, overgrazing, excavation, etc. The essence is that the soil structure is destroyed and transformed into sandy soil. During this process, the humus in the soil decreases, and the agglomerated soil gradually granulates, forming sand particles with a particle size of 0.05-1mm. Sandy soil has large pores between particles, few small pores, and weak capillary action, re...
