Problems solved by technology

How to overcome the problems of long transplanting period and high cost of sweet corn seedlings, it is of great significance to explore and formulate a set of simple and practical cultivation techniques that can significantly improve the efficiency and survival rate of seedling raising and transplanting
In recent years, corn research workers have successively carried out the research on the substrate and transplanting method of fresh corn seedlings, such as the invention patent with the application publication number of CN 107873432A, which specifically discloses a corn seedling raising method that promotes rooting by stress hardening seedlings. The survival rate of transplanting has been improved to a certain extent, but the water and fertilizer control in the seedbed is difficult to cause the emergence of large and small seedlings. After transplanting into the fie

Embodiment 1

[0026] This embodiment is a method for accelerating germination and raising seedlings of sweet corn in a sand bed provided by the present invention, comprising the following steps:

[0027] (1) Prepare the seedbed: place a seedling pot (60cmx30cm) in the planting field, and then cover the construction river sand with a thickness of 2cm and a diameter of 0.1cm in the seedling pot to form a seedbed;

[0028] (2) Sowing: Sprinkle the sweet corn seeds evenly on the seedbed described in step (1), gently press the sweet corn seeds with the palm of your hand so that the sweet corn seeds fit the seedbed, and then cover a layer of 0.1 cm in diameter with a thickness of 0.1 cm. cm construction river sand, then cover with a layer of straw, then drench the seedbed with water, then cover the seedbed with black agricultural mulch, and compact the periphery of the black agricultural mulch to ensure that the seedbed is in a relatively closed environment;

[0029] (3) Management after sowing: ...

Embodiment 2

[0032] This embodiment is a method for accelerating germination and raising seedlings of sweet corn in a sand bed provided by the present invention, comprising the following steps:

[0033] (1) Prepare the seedbed: place a seedling pot (60cmx30cm) in the planting field, and then cover the building river sand with a thickness of 3cm and a diameter of 0.2cm in the seedling pot to form a seedbed;

[0034] (2) Sowing: Sprinkle the sweet corn seeds evenly on the seedbed described in step (1), gently press the sweet corn seeds with the palm of your hand so that the sweet corn seeds fit the seedbed, and then cover a layer of 0.2 cm in diameter with a thickness of 0.2 cm. cm construction river sand, then cover with a layer of straw, then drench the seedbed with water, then cover the seedbed with black agricultural mulch, and compact the periphery of the black agricultural mulch to ensure that the seedbed is in a relatively closed environment;

Abstract

The invention relates to a sand bed germination accelerating and seedling raising method for sweet corn, and belongs to the technical field of agricultural planting. According to the sand bed germination accelerating and seedling raising method for the sweet corn, the sweet corn is sown in a fine sand seedbed, a transplanting mode of sweet corn seedlings is changed into a root seedling transplanting germination accelerating and seedling raising method, the seedbed formed by building fine sand has good hydrophobic and breathable effects, the time of breaking the soil by the seeds is shortened, and the germination rate of the seeds is increased. The method is simple to operate, can ensure that the seedling emergence uniformity and the field survival rate of the sweet corn are consistent with those of the conventional nutrition pot seedling raising effect on the basis of greatly shortening the transplanting period and greatly shortening the seedling raising and transplanting cost, and has wide practical and popularization values in the aspects of sweet corn tests and commercial production.

Description

technical field [0001] The invention relates to a method for accelerating germination and raising seedlings of sweet corn in a sand bed, belonging to the technical field of agricultural planting. Background technique [0002] Corn (Zea mays L.) is corn, also known as corn, corn, cob, etc., and corn belongs to the genus Zea in the grass family. It is generally believed that the ancestor of corn was teosinte, which originated in South America. In 2009, the sown area and output of corn in my country surpassed that of rice, becoming the largest crop in my country. USDA data shows that from 2000 to 2020, the global corn production showed a steady growth trend. In 2020, the global corn production was 1,136.31 million tons, nearly double that of 2000, with an average annual growth rate of 3.4%. Among them, the United States accounted for 34.86%, China accounted for The proportion is 25.22%, and it has long been the largest producer and the second largest producer of corn in the w...
