Method for late sowing and cultivating yam in arid desert soil area by integrating water and fertilizer

Abstract

The invention relates to a method for late sowing and cultivating yam in an arid desert soil area by integrating water and fertilizer, and belongs to the technical field of crop cultivation. The method includes the following steps: 1. land block selection; 2. seed preparation; 3. soil preparation and fertilization; 4. seed sowing; 5. frame erecting; 6. vine guiding; 7. weeding; 8. irrigation and topdressing; 9. pest control; and 10. Harvesting. The method is a scientific method for timely sowing yam in the arid desert soil area based on the growth habit of yam, the sowing time of yam is delayed, and the late frost and windy weather are missed, and thus the method can ensure timely and regular emergence of the yam after sowing, high yield, excellent quality, excellent taste, high medicinalhealth care value and high economic benefit of the yam.

Description

technical field [0001] The invention relates to a method for late sowing and cultivating yam in arid desert soil area with integrated water and fertilizer, belonging to the technical field of crop cultivation. Background technique [0002] Desert soil is the soil developed in desert areas with arid, little rainfall and sparse vegetation. China's desert land is located in the temperate zone and warm temperate zone, with long sunshine and sufficient heat. As long as there are irrigation water sources and facilities and attention is paid to the prevention and control of drought, sandstorms and salinity hazards, fertile oases and superior grasslands can be built. Among them, the gray desert area can be used for agricultural production, and the brown desert and gray-brown desert areas are suitable for camel grazing. [0003] Yam, also known as yam, yam, long taro, etc., is a crop of the Dioscoreaceae family, and is an annual or perennial entwining vine. The main product is the f...

Problems solved by technology

[0005] Yam planting in arid desert areas generally starts in mid-April, but if the late frost cools down from late April to early May, causing the temperature to drop below 0°C, the seed potatoes will be damaged by freezing

In addition, from April to mid-May, it is the most serious season of sandstorms in desert areas. Due to the dry soil and soil disturbance during planting yams, while further increasing the possibility of wind erosion of the topsoil, the sown seed potatoes will be destroyed. The wind blows out, causing waste of seed potatoes, labor, etc.
