Embodiment 1

[0026] Experimental location: a dry slope in Nanping County, Guigang City, Guangxi, at an angle of 15° to the horizontal plane

[0027] Planting variety: Guihuai No. 6 yam seeds

[0028] Experimental steps:

[0029] (1) Use a tractor rotary tiller to operate at a depth of 15 cm to crush the surface of dry slopes or mountains.

[0030] (2) According to the row spacing of 1.2 meters, a longitudinal strip ditch with a width of 25 cm and a depth of 25 cm is opened from the upper part to the lower part of the hard soil at the bottom of the plow.

[0031] (3) Cut the hard plastic according to the width and length of 25 cm depending on the length of the upper and lower parts of the planting ground, then lay the cut hard plastic from top to bottom, straighten and fix it, and pay attention to the proper thickness of the bottom on both sides of the hard plastic film. The height of the pad is 2 cm, so that the hard plastic material film is in a shallow "concave" shape. The hard plasti...

Embodiment 2

[0038] Experimental location: a mountainous area in Wenxian County, Jiaozuo, Henan Province, at an angle of 20° to the horizontal plane

[0039] Planting varieties: iron stick yam

[0040] Experimental steps:

[0041] (1) Use a tractor rotary tiller to operate at a depth of 20 cm to crush the surface of dry slopes or mountains.

[0042] (2) According to the row spacing of 1 meter, open a longitudinal strip ditch with a width of 28 cm and a depth of 28 cm from the upper part to the lower part of the hard soil at the bottom of the plow.

[0043] (3) Cut the hard plastic film according to the width and length of 28 cm depending on the length of the upper and lower parts of the planting ground, and then lay the cut hard plastic film from top to bottom, straighten and fix it, pay attention to both sides of the hard plastic film Properly raise the bottom by 1 cm, so that the hard material film is in a shallow "concave" shape. The hard plastic film is high-density polyethylene.

Embodiment 3

[0050] Experimental location: a dry slope in Yongning County, Yinchuan, Ningxia, at an angle of 5° to the horizontal plane

[0051] Planting varieties: high-yielding golden yam

[0052] Experimental steps:

[0053] (1) Use a tractor rotary tiller to operate at a depth of 10 cm to crush the surface of dry slopes or mountains.

[0054] (2) According to the row spacing of 1.1 meters, a longitudinal strip ditch with a width of 26 cm and a depth of 26 cm is opened from the upper part to the lower part of the hard soil at the bottom of the plow.

[0055] (3) Cut the hard plastic film according to the width and length of 26 cm depending on the length of the upper and lower parts of the planting ground, then lay the cut hard plastic film from top to bottom, straighten and fix it, pay attention to the sides of the hard plastic film The bottom is appropriately raised by 1.5 cm, so that the hard material film is in a shallow "concave" shape. The hard plastic film is plastic colored st...

Abstract

The invention discloses a cultivation method for Huaishan longitudinal strip directional tuberization, which uses a tractor and a rotary to work on dry hillside or mountain land of 10o to 20o. After the plowing of the surface soil shallow, through the laying of hard plastic film, Huaishan grows directionally under the guidance. The specific steps comprise: rotary tilling and preparing the land, opening vertical strip ditches, laying hard plastic film, backfilling and fertilizing, planting Huaishan seeds, and managing fields and harvesting. The cultivation method for Huaishan longitudinal strip directional tuberization is capable of achieving the directional tuberization of Huaishan and the whole process is simple and easy to save time and effort. The Huaishan potato strips of the production are thick and big, round and straight with high production and commodity. At the same time, the full use of dry hillside and mountain land and other land resources is not only capable of playing the existing ecological and economic potential of dry hillside and mountain land, but also alleviating the current status that the shortage of cultivated land resources in China.

Description

technical field [0001] The invention relates to a method for cultivating economic crops, in particular to a method for directional tuber cultivation of Chinese yam. Background technique [0002] Huaishan (Dioscorea opposita Thunb.) is also known as Huai Yam, Huai Yam, Potato, Sweet Potato, Sweet Potato, and Yuyan. It is the dry rhizome of yam yam. Huaishan is rich in nutrition and has a good therapeutic effect. In recent years, people have paid more and more attention to nutrition and health, and Chinese yam has also been sought after by people. The demand for yam began to exceed supply, and the price gradually increased. Therefore, how to scientifically plant Chinese yam is a topic worth studying. [0003] Zhunshan tuber has the characteristic of natural growth downwards. Huaishan tubers grow underground, and some can be as long as one meter. Therefore, the traditional Huaishan planting technology requires deep trench planting and deep digging for harvesting, which is l...
