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) Fertilization for site preparation: 50kg / mu compound fertilizer (N:P:K=15:6:9) and 150kg / mu granular organic fertilizer were evenly spread in the seedling shed, and rotary tillage was used for leveling.

[0060] (2) Row seed potatoes: set up field furrows, each furrow width is 90cm, length is 45m, a 45cm blank channel is left between the furrows, the distance between seed potatoes is 2cm, and the seeding density is 10kg / m 2 .

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

[0062] (4) Covering soil: After the drip irrigation belt is laid, take soil directly from the blank channel between the furrows and cover it on the seed potatoes and the drip irrigation belt.

[0063] (5) Covering with plastic film: Cover the high furrows with 0.1mm thick black plastic film, ...

Embodiment 2

[0068] (1) Fertilization for soil preparation: Evenly spread 100kg / mu compound fertilizer (N:P:K=15:6:9) and 200kg / mu granular organic fertilizer in the seedling shed, and then level it with rotary tillage.

[0069] (2) Row seed potatoes: set up field furrows, each furrow width is 95cm, length is 50m, a 50cm blank channel is left between the furrows, the distance between seed potatoes is 2.5cm, and the seeding density is 11kg / m 2 .

[0070] (3) Spread drip irrigation tape: After the seed potatoes are arranged, lay the drip irrigation tape directly on the seed potatoes, with the outlet of the drip irrigation tape facing down, and the distance between the drip irrigation tapes is 28cm.

[0071] (4) Covering soil: After the drip irrigation belt is laid, take soil directly from the blank passage between the furrows and cover it on the seed potatoes and the drip irrigation belt. The thickness of the covering soil is 4.5cm, and finally a high furrow with a height of 45cm is formed, ...

Embodiment 3

[0077] (1) Fertilization for soil preparation: Evenly spread 150kg / mu compound fertilizer (N:P:K=15:6:9) and 250kg / mu granular organic fertilizer in the seedling shed, and level off with rotary tillage.

[0078] (2) Row seed potatoes: Set up field furrows, each furrow width is 100cm, length is 45m, a blank channel of 55cm is left between the furrows, the distance between seed potatoes is 3cm, and the seeding density is 12kg / m 2 .

[0079] (3) Spread drip irrigation tape: After the seed potatoes are arranged, lay the drip irrigation tape directly on the seed potatoes, with the outlet of the drip irrigation tape facing down, and the distance between the drip irrigation tapes is 30cm.

[0080] (4) Covering soil: After the drip irrigation belt is laid, take soil directly from the blank passage between the furrows and cover it on the seed potatoes and the drip irrigation belt.

[0081] (5) Covering with plastic film: Cover the high furrows with 0.15mm thick black plastic film, wit...

Abstract

The invention belongs to the technical field of sweet potato strong seedling cultivation, and provides a sweet potato high-ridge drip irrigation strong seedling cultivation method. The method comprises the steps of soil preparation and fertilization, potato seed arrangement, drip irrigation tape laying, soil covering, mulching film covering, watering and pesticide dripping, mulching film removing, seedbed management and the like. According to the method, the problems of high labor cost, high potato rotting probability, late seedling emergence, high workload and the like in the traditional potato seed seedling raising technology are solved. By the adoption of the method, labor input can be saved, labor intensity can be reduced, farming operation is more convenient, soil permeability can be improved, seedling emergence time can be remarkably shortened, the seedling emergence number of the potato seeds can be increased, and the disease incidence rate of the potato seeds can be remarkably reduced.

Description

technical field [0001] The invention relates to the technical field of cultivating strong seedlings of sweet potatoes, in particular to a method for cultivating strong seedlings of sweet potatoes with high border drip irrigation. Background technique [0002] Sweet potato is an important food crop in my country. Planting potato seedlings in the field is an important and necessary link in sweet potato production. More than 80% of the seedlings for planting sweet potato in the field come from seedling cultivation of sweet potato. [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 seedbeds, arranging seed potatoes, covering soil, watering, and covering with film. 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 s...
