The experimental methods described in the following examples are all conventional methods unless otherwise specified; the reagents and materials are commercially available, unless otherwise specified.
The main material sugarcane variety of the invention is Yunzhan 05-51, and the examined and numbered Guiju sugarcane 2014012 can be purchased from the market.
Example 1
A method for preparing a sugarcane single-bud coating comprises the following steps:
step one, uniformly mixing 1 part by weight of chitosan oligosaccharide and 1 part by weight of chitosan to obtain a first coating agent for later use;
and step two, mixing hydroxyethyl cellulose, carboxymethyl cellulose and water according to the mass ratio of 1.
Step three, mixing sodium naphthalene acetate, compound sodium nitrophenolate and water according to the ratio of 1:1, and soaking the sugarcane single-bud stem seeds for 12 hours for later use after uniformly mixing the components in a mass ratio of.
And step four, spraying the adhesive obtained in the step two and the first coating agent obtained in the step one on the surface of the single-bud seed stem of the sugarcane prepared in the step three to prepare the single-bud coated sugarcane seed.
Comparative example 1
The same sugarcane variety (Yun Zhe-51) is planted on the same test field, the planting means and the management method are the same, the difference is that the same test field is divided into A, B, C test fields, the bud number of the sugarcane per mu is 6000 buds, A test field is the sugarcane single-bud coated seed of the invention, B is the sugarcane single-bud seed stem without any treatment, and C is the conventional seed stem of the sugarcane region. The results are shown in Table 1.
TABLE 1 sugarcane emergence and yield constitutive factors
According to experimental data, the seedling emergence, yield construction factors and final yield of the sugarcane are higher than those of the sugarcane processed by the B processing and the C processing, the yield of the sugarcane processed by the single-bud coated seeds is highest, the quality of the sugarcane buds can be ensured by the single-bud processing, the germination rate is high, and phenomena of ridge shortage, line breaking and the like frequently occur in double-bud and whole-stem sugarcane seeds commonly used in sugarcane areas, so that the seedling quantity, the effective stems and the yield of the sugarcane are influenced.
