Problems solved by technology

[0005] The existing waxy corn planting has low yield due to drought and dog weather. At the same time, unreasonable close planting will cause the waxy corn population and individuals to not develop in harmony, resulting in insufficient light, so that high-yield corn cannot be obtained.
[0006] In the existing waxy corn fertilization process, there is a lack of consideration of regionality, seasonality, and growth stages of waxy corn, and the level of fertilization is not good in terms of the nutrient requirements of waxy corn growth;
[0007] On the one hand, fertilization has been overly dependent on chemical fertilizers, and the amount of organic fertilizers is less;
[0008] On the other hand, the proportion of nitrogen fertilizer, phosphorus fertilizer and potassium fertilizer is extremely unreasonable, and the amount of phosphorus fertilizer and potassium fertilizer is seriously insufficient; resulting in high lodging rate and stem rot incidence of waxy corn and weak yield, quality and market competitiveness
[0009] And prior art lacks related industry to the development and utilization of waxy corn

Embodiment Construction

[0061] In order to make the object, technical solution and advantages of the present invention more clear, the present invention will be further described in detail below in conjunction with the examples. It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.

[0062] The existing glutinous corn planting has low yield due to drought and dog weather, and unreasonable close planting will make the waxy corn population and individuals unable to coordinate development, resulting in insufficient light, so that high-yield corn cannot be obtained.

[0063] Such as figure 1 As shown, the high-yield cultivation method for transplanting film-mulched waxy corn provided by the embodiments of the present invention comprises the following steps:

[0064] S101: seed preparation;

[0065] S102: Preparation of nutrient soil;

[0066] S103: Seedbed preparation; choose leeward to the sun, plow th...

Abstract

The invention belongs to the technical field of agricultural planting and discloses a high-yield cultivation method of waxy corn based on transplanting and mulch, comprising: preparing seeds; preparing nutrient soil; preparing a seedbed field; applying sufficient base fertilizer; sowing and growing seedlings; managing seedbeds; transplanting in due time; applying sufficient topdressing. The methodof the invention has the advantages that large-scale production of waxy corn is effectively increased; directional transplanting provides increased density and high yield; early sowing and seedling growth and due-time transplanting help shorten the growth period, maturation is earlier , the influence of dog days or drought is avoided, and stable and high yield is achieved; about 1 jin of seed isadded per mu based on existing production according to the requirements of high-yield waxy corn, that is to say, the planting density per mu is increased by 800-1200 plants of waxy corn, effective earnumber per mu is 3000-4000, single-ear grain weight is 140-180 g, and the yield of waxy corn per mu is 800-1000 jin.

Description

technical field [0001] The invention belongs to the technical field of agricultural planting, and in particular relates to a high-yield cultivation method for transplanting film-mulched waxy corn. Background technique [0002] At present, the existing technologies commonly used in the industry are as follows; [0003] Waxy corn, also known as waxy corn. Waxy corn originated in China. After maize was introduced into China, the hard maize planted in Southwest China mutated, and the waxy type gradually appeared through artificial selection. Judging from the scientific name Zea mays L. sinensis Kulesh, it means "Chinese species". Waxy corn kernels have a thicker, waxy endosperm, more like the shiny, glassy (transparent) kernels of hard corn and dent corn. Its chemical and physical traits are controlled by a single recessive gene (wx), which is located on chromosome 9. 100% of the starch in the endosperm is amylopectin (Amylopectin or Branched chain starch). In addition to...
