Description

Method for coating manure of elymus cloaca and ryegrass seeds

Technical Field

The invention belongs to the technical field of pasture planting, and particularly relates to a coating method for alkali grass and ryegrass seed manure.

Background

The green sea grass (school name: elymus geminata (Keng et s.l. Chen) l.liou) was approved by the national grass flat seed approval committee in 1989, and the department of agriculture approved the name, granting popularization of planting in the adapted area. The green-sea grass is a perennial grass plant of Gramineae, has the characteristics of drought resistance, cold resistance, wind sand resistance, nicotine resistance, barren resistance, wide adaptability and the like, and is a good plant for water and soil conservation and improvement. The stem height is 70-140 cm, and the stem is in a loose cluster shape. Leaf sheath is longer than internode. Blade-shaped, often with greenish powder. The spike is 14-20 cm long, and each node usually produces 2 spikelets containing 3-5 flowers. The glume is slightly shorter or equal to the first flower. The back of the palea and the basal disc are used for growing small coarse hairs, and the palea of 1-2 cm is jacked.

Ryegrass (school name: triticosale), which is a annual or perennial herb of Gramineae, is a kind of ryegrass, has developed root system, extremely strong tillering capability, fast growth, drought resistance, strong drought resistance, high plant size and high yield, and is one of high-yield pasture varieties which are successfully planted at high altitude.

Artificial reseeding and planting of grass varieties suitable for local natural climate conditions is one of the important means of current restoration and reconstruction of moderately and severely degraded grasslands. However, most degraded grasslands, especially severely degraded grasslands, suffer from damage to soil structure, loss of soil nutrients, and reduced water holding capacity, resulting in limited germination capacity of the planted exogenous seeds. In addition, the method is suitable for large-scale sowing of excellent pasture varieties in high-altitude cold drought areas, such as the grass of the green sea, and most seeds are light in weight and easily sealed and scattered during sowing, so that sowing efficiency and seed germination capacity are affected.

Detailed Description

The specific technical scheme of the invention is described by combining the embodiments.

1. Coating material preparation, as shown in fig. 1:

the coating material comprises air-dried cow dung, air-dried sheep dung and water-retaining agent. Coating materials were formulated as substrates in different proportions: 100% of cow dung, 100% of sheep dung, 50% of cow dung, 50% of sheep dung, 95% of cow dung, 5% of water-retaining agent, 95% of sheep dung and 5% of water-retaining agent;

and preparing coating seeds with different particle diameters (1 cm, 2cm, 3cm and 4cm respectively) and different numbers of coated seeds (1 grain, 2 grain, 3 grain and 4 grain respectively) by using the prepared adhesive (the diluted mass concentration of the carboxypropyl methyl cellulose is 37.5%), drying in the shade for 2-3 days to form hard solids, and sowing in a flowerpot with the thickness of 20.5cm multiplied by 48.5cm for cultivation. 20 coated seeds were sown per pot. And (3) in the cultivation process, watering regularly and quantitatively, and measuring.

2. And (3) result statistics:

(1) Plant height

Experimental researches on the preparation of different particle sizes and different seed coating particle numbers by using cow dung and water-retaining agents with different proportions as matrixes show that the plant height is obviously influenced by the coating matrixes, the coating particle sizes and the coating seed particle numbers, and interaction between every two treatments is obvious, as shown in table 1.

Table 1 shows the independent and interactive effects of different coating matrices, coating particle sizes, and numbers of coated seeds on plant height, number of seedlings and time of emergence for the multi-factor analysis of variance results.

FIG. 2 shows the effect of different coating matrices and particle sizes on plant height. Control-Control group; s100-100% of sheep manure; S45Y45W 5-sheep manure 45% + cow manure 45% + water-retaining agent 10%; S95W 5-sheep manure 95% + water retention agent 5%; y100-cow dung 100%; Y50S 50-50% of sheep manure and 50% of cow manure; Y95W 5-cow dung 95% + water-retaining agent 5%. Particle size (Diameter): 0-no coating; particle size of 1-1 cm; particle size of 2-2 cm; particle size of 3-3 cm; particle size of 4-4 cm.

FIG. 3 shows the effect of different coating matrices and seed particle counts on plant height. Control-Control group; s100-100% of sheep manure; S45Y45W 5-sheep manure 45% + cow manure 45% + water-retaining agent 10%; S95W 5-sheep manure 95% + water retention agent 5%; y100-cow dung 100%; Y50S 50-50% of sheep manure and 50% of cow manure; Y95W 5-cow dung 95% + water-retaining agent 5%. Seed number (seed): 1-1 seed; 2-2 seeds; 3-3 seeds; 4-4 seeds.

FIG. 4 shows the effect of different coating matrices and seed particle counts on the number of seedlings emerging from the seeds. Control-Control group; s100-100% of sheep manure; S45Y45W 5-sheep manure 45% + cow manure 45% + water-retaining agent 10%; S95W 5-sheep manure 95% + water retention agent 5%; y100-cow dung 100%; Y50S 50-50% of sheep manure and 50% of cow manure; Y95W 5-cow dung 95% + water-retaining agent 5%. Seed number (seed): 1-1 seed; 2-2 seeds; 3-3 seeds; 4-4 seeds.

Only sheep manure, sheep manure 95% + water retention agent 5% or cow manure 95% + water retention agent 5% as coating matrix significantly improved plant height as shown in fig. 2 and 2 compared with control and other matrix conditions. The grain size of over 2cm is compared with the control, the plant height is obviously improved, but the difference among the grain sizes of 2, 3 and 4cm is not obvious as shown in figure 2. At average, the plant height was relatively higher at 3 coated seeds than at other coated seeds as shown in fig. 3.

2.2 number of seedlings

The number of coating matrix and coating seeds significantly affected the number of seedlings, but the size of the coating particle size did not significantly affect the number of seedlings, but showed significant interactions between treatments as shown in table 1. Although all the coated substrates resulted in a significant reduction in the amount of elymus chinensis and oat seedlings at the average coating particle size, coated seed amount, as shown in table 2, the presence of either 95% sheep manure +5% water retention agent or 95% cow manure +5% water retention agent as coated substrate significantly increased the number of plant seedlings compared to the control on the 3 coated seed amount as shown in fig. 4.

2.3 time to emergence of seedlings

The coating matrix significantly affected the time to emergence, i.e., the amount of time from seeding to emergence, but the coating particle size, the number of coated seed particles, and the interaction between treatments did not significantly affect the time to emergence, as shown in table 1. When only 50% of cow dung or sheep dung +50% of cow dung was used as the coating matrix, the emergence time was significantly delayed compared to the control, as shown in table 2. Other substrate conditions did not significantly affect the emergence time, but the emergence time tendencies were shown to be earlier than the control when only sheep manure, sheep manure 95% + water retention agent 5% or cow manure 95% + water retention agent 5% were used as the coating substrate, as shown in table 2.

Table 2 shows the independent and interactive effect of different coating matrices (treatments) on plant height, number of seedlings and time of emergence for the mixed linear model analysis results.

TABLE 2

3. Conclusion(s)

The results of the researches show that when the coating matrix is 95 percent of sheep manure plus 5 percent of water retention agent or 95 percent of cow manure plus 5 percent of water retention agent, compared with the control, the plant height and the emergence rate (the number of coating particles is 3) are improved, and the emergence is advanced. And the plant height is obviously improved by the control (without coating) with the particle size of 2cm and the coating with the particle size of 1 cm. Therefore, in the embodiment, the sheep manure 95% + water-retaining agent 5% or the cow manure 95% + water-retaining agent 5% are selected as the coating matrix, the 2cm coating is used as the particle size, and 3 seeds are coated as the seed coating quantity to be used as a preferable scheme.
