Embodiment 1

[0026] The inventor carried out the demonstration and extension of yam longitudinal zone directional winter planting and summer harvest in a village in Dingxing County, Baoding, Hebei. The demonstration plot was 95.33m in length and 65.32m in width. , the specific operation steps are;

[0027] (1) Put the twin yams harvested on October 20, 2013 at a low temperature of 5-7°C for sleep suppression treatment until October 5, 2014, and then take them out for winter planting and summer harvest kind.

[0028] (2) Hypnosis suppression and germination treatment of yam seed potatoes: On October 6, 2014, the yam seed potatoes that had undergone low-temperature sleep suppression treatment were disinfected and germination treatment: the yam seed potatoes were cut into pieces and placed at 8-15 mg / L Gibberellin and 2 mg / L 50% carbendazim aqueous suspension solution, control the temperature at 17°C-25°C, treat for 30 minutes, take out the seed potatoes and dry them in the air.

[0029] (3...

Embodiment 2

[0035] The inventor carried out the demonstration and popularization of the Chinese yam vertical zone directional winter planting and summer harvest in a county farm in Zhangye City, Gansu Province. The length of the demonstration plot is 177.54m, the width is 125.89m, and it is north-south. For many years, due to the difficulty of controlling weeds, we changed to winter yam. The specific operation steps are as follows;

[0036] (1) The twin yams harvested on November 20, 2012 were placed at a low temperature of 6°C for sleep suppression treatment until October 5, 2013, and then taken out for winter planting and summer harvest.

[0037] (2) Hypnosis suppression and germination treatment of yam seed potatoes: On October 31, 2013, the yam seed potatoes that had undergone low-temperature sleep suppression treatment were disinfected and germination treatment: the yam seed potatoes were cut into pieces and placed at 8-15 mg / L Gibberellin and 2 mg / L 50% carbendazim aqueous suspensio...

Embodiment 3

[0044] The inventor also carried out the demonstration and promotion of directional winter planting and summer harvest in the Huaishan longitudinal belt in Jiyang County, Jinan, Shandong Province. The length of the demonstration plot is 295.33m, the width is 55.72m, and it is east-west. Wheat and corn were planted before. The price of corn has fallen severely, and the income of farmers in the demonstration area has decreased. They have changed to Huaishan. The specific operation steps are as follows:

[0045] (1) The Guihuai No. 2 yam harvested on November 2, 2012 was placed at a low temperature of 5-7°C for sleep suppression treatment until November 6, 2013, and then taken out for winter planting Seeds for summer harvest.

[0046] (2) Hypnosis suppression and germination treatment of yam seed potatoes: On October 31, 2013, the yam seed potatoes that had undergone low-temperature sleep suppression treatment were disinfected and germination treatment: the yam seed potatoes were...

Abstract

The invention provides a longitudinal belt directed winter-planting and summer-harvesting planting method for dioscorea opposita thunb.. A winter-planting and summer-harvesting planting mode is adopted that dioscorea opposita thunb. is sown and planted in dry land and gentle slope land in October-November and harvested in May-June the second year. The method comprises the steps of: 1, performing sleep suppression treatment, such as low temperature treatment, on dioscorea opposita thunb. seed yams; 2, mechanically digging planting furrows and laying color strip belts or other hard materials; 3, performing disinfection and germination accelerating treatment on the seed yams; 4, placing the seed yams and covering the seed yams with soil to form beds or ridges; 5, building simple thermal-insulation small arch sheds along the beds or ridges; 6, performing field management; 7, performing harvesting. The method can increase efficiency, utilize winter idle land, increase income for farmers, supply a great amount of dioscorea opposita thunb. to the market in the gap period of summer, meet the consumption requirements of people and promote rapid development of the planting industry of dioscorea opposita thunb.. The longitudinal belt directed planting technology is adopted and small machines can be used for planting groove ditching and soil clearing, so that the operations in planting and harvesting are convenient, manual work can be reduced, costs can be reduced and income can be increased.

Description

technical field [0001] The invention relates to a method for cultivating economic crops, in particular to a method for directional planting of Chinese yam in longitudinal belts for planting in winter and harvesting in summer. Background technique [0002] Huaishan (Dioscorea opposita Thunb.) is also known as Huai Yam, Huai Yam, Potato, Yam, Yam, 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 ...
