Embodiment 1

[0021] The dryland sweet potato water-saving efficient planting method of the present embodiment, the method is:

[0022] S1, variety selection: the variety of sweet potato is Qinshu No. 5, a short-vine variety with early expansion;

[0023] S2. Deep plowing time: deep plowing of the soil after the harvest of autumn corn or soybean autumn crops, the plowing depth is 35cm, breaking the soil and plowing the stratum;

[0024] S3, selection of sweet potato seedlings: select the first crop of healthy and strong seedlings in the seedling shed as sweet potato seedlings; the selection criteria for sweet potato seedlings are: the weight of 100 seedlings is greater than 0.75kg, the seedling height is 18cm~22cm, and the internode is 3 1 to 4, seedling stem diameter is 0.3cm to 0.4cm, no aerial roots, no pests and diseases;

[0025] S4, soil preparation and ridging: after the first rainfall greater than 12 mm in early spring, apply 10% diazinon granule of 1 kg / mu, then combine moisture a...

Abstract

The invention provides a water-saving and a high-efficient planting method for a sweet patato in dry land. The water-saving and high-efficient planting method for sweet patato in dry land comprises the following steps: early swelled sweet patatoes of short-vine variety are selected, deep ploughing is carried out after autumn harvest of corn or soybean, ploughing depth is 35 cm-40 cm, the first healthy and strong seedlings in a seedling shed are selected as sweet patato seedlings, soil is fertilized, ridged and coated with film after a first rainfall with rainfall capacity of more than 12mm inearly spring and spraying pesticides, when soil temperature in the film is at 12 DEG C to 15 DEG C in mid-April, stem bases of the sweet patato seedlings at the position of 10cm are soaked with a 20%triazophos microcapsule suspension agent, then the sweet patato seedlings are planted, are chemically weeded after 25 d-30 d of plantation, and are harvested in early August to obtain sweet patatoes.The core method for the water-saving and high-efficient planting method for sweet patato is ''one high and seven early'', ''high'' means high planting density, "early" means deep ploughing, early ridging and film coating, early planting, early tuber forming, early weeding, and early harvest, all natural rainfalls are stored in the soil for growth of sweet patatoes, high-efficient untilization of the natural rainfalls is realized, and high-yield plantation of sweet potatoes in dry land is realized.

Description

technical field [0001] The invention belongs to the technical field of sweet potato planting, and in particular relates to a water-saving and high-efficiency planting method of sweet potato in dry land. Background technique [0002] The Weibei plateau area in Shaanxi is a typical dryland agricultural production area. In this area, water resources are short, soil erosion is serious, crop yield is low and unstable, and production efficiency is not high. Sweet potato has a well-developed root system, strong fertilizer absorption and drought tolerance, and a high utilization rate of water and fertilizer in dry farming areas. Especially the promotion of plastic-filmed sweet potatoes has high yield and good benefits. Compared with other crops, it has obvious advantages in production. get faster development. However, the production of sweet potato is limited by traditional cultivation techniques, the loss of natural precipitation is large, the production efficiency is low, and the...
