Problems solved by technology

However, there are certain deficiencies in the above-mentioned traditional seed potato seedling raising technology: firstly, the depth of digging about 15 cm is required to build the seedling bed, and labor costs are required; The soil is compacted, the permeability is poor, and the probability of rotten potatoes increases; thirdly, the bed soil and surrounding soil are wet and sticky after watering, and the plastic film cannot be covered immediately, which affects the increase of ground temperature and delays the emergence time; It is necessary to bend down to operate when seedling, which increases the workload, etc.

Embodiment 1

[0059] (1) Field preparation and fertilization: Evenly spread 50kg / mu of compound fertilizer (N:P:K=15:6:9) and 150kg / mu of granular organic fertilizer in the nursery shed, and rotate and level.

[0060] (2) Seed potato rowing: Set up field borders, each border is 90cm wide and 45m long, with 45cm of blank passages left between the borders, the spacing of seed potatoes is 2cm, and the seeding density is 10kg / m 2 .

[0061] (3) Lay the drip irrigation tape: After the seed potatoes are arranged, lay the drip irrigation tape directly on the seed potatoes, with the water outlet of the drip irrigation tape facing down, and the distance between the drip irrigation tapes is 25cm.

[0062] (4) Cover soil: After the drip irrigation belt is laid, take soil directly from the blank channel between the borders to cover the seed potatoes and the drip irrigation belt with a thickness of 4cm, and finally form a high border with a height of 40cm, and the furrow and ditch are neatly repaired. ...

Abstract

The invention belongs to the technical field of cultivating strong seedlings of sweet potato, and provides a method for cultivating strong seedlings by drip irrigation on high borders of sweet potato. The method of the invention includes the steps of soil preparation and fertilization, seed potato rowing, drip irrigation tape laying, soil covering, mulching film covering, watering and dripping medicine, mulching film removal, seedbed management and the like. The method of the invention solves the problems of high labor cost, high probability of rotten potato, late emergence, large workload and the like existing in the traditional seed potato seedling raising technology. The method of the invention not only saves labor input, reduces labor intensity, and is more convenient for agricultural operations, but also helps to increase soil permeability, significantly shortens the emergence time, increases the number of seed potatoes emerging, and significantly reduces the disease-susceptibility rate of seed potatoes.

Description

technical field [0001] The invention relates to the technical field of cultivating strong seedlings of sweet potato, in particular to a method for cultivating strong seedlings of sweet potato by drip irrigation. Background technique [0002] Sweet potato is an important food crop in my country. The planting of potato seedlings in the field is an important and necessary link in sweet potato production. More than 80% of sweet potato field planting seedlings come from sweet potato seedlings. [0003] The traditional process of breeding seedlings with sweet potato seeds includes building greenhouses or sheds in spring and autumn, soil preparation and fertilization, building seedling beds, rowing seed potatoes, covering soil, watering, and covering films. However, the above-mentioned traditional potato seedling raising techniques have certain shortcomings: first, the construction of the seedling bed needs to be dug down to a depth of about 15cm, which requires labor costs; The...
