Project Description
HPP-2S Potato Plant Machine Introduction
Potato is a staple food and cash crop. Traditional planting methods involve complicated procedures and high labor costs. Conventional potato planters adopt the “seeding first, mulching later” process, which requires massive labor to manually tear film for seedling emergence and secondary soil covering after sprouting. In hot weather, sprouts are easily scalded under the film, severely restricting large-scale farm production.
Manufactured by HUAYO AGRO Agricultural Machinery, the Model HPP-2S Potato Plant Machine features an innovative integrated workflow: ridge forming → drip tape laying → plastic mulching → film-top duckbill seeding. It integrates side deep fertilization, standard ridge forming, drip tape installation, automatic mulch laying, precise duckbill punching seeding and automatic hole backfilling. No manual film tearing or secondary soil covering is required, thoroughly solving labor shortages in potato farms. It is the preferred agricultural machine for standardized planting in professional potato cooperatives and large-scale growing bases.

Core Innovative Workflow: Mulch First, Then Film-Top Duckbill Seeding (Differentiating Advantage)
Most potato planters on the market seed before mulching. Trapped sprouts under sealed film get easily burnt by high temperature, and farms have to hire workers to manually cut mulch and refill holes with extra soil, pushing up labor expenses per mu.
The Model HPP-2S Potato Plant Machine adopts a reversed combined operation process. One single tractor pass completes all planting steps in sequence:
- Ridge shapers till soil and form standard 200 mm high ridges;
- Drip tape reels lay irrigation lines simultaneously to deliver water and fertilizer directly to tuber roots for water-saving yield growth;
- Mulch laying frames spread plastic film automatically, with side press wheels covering film edges with soil to fix mulch tightly against ridges;
- Rear duckbill seeding units pierce the mulch vertically and place seed tubers at accurate depth;
- Mini backfill shovels refill and seal seeding holes instantly.
No manual film cutting or secondary soil covering is needed after one pass. Seedlings grow naturally through reserved duckbill holes, eliminating two labor-intensive working procedures and greatly cutting farm labor costs.
Five Major Advantages of Film-Top Duckbill Seeding
1 Avoid Sprout Scalding, Uniform Emergence & Higher Commercial Potato Yield
Full plastic mulch retains soil temperature and moisture. Seed tubers stay buried under film without risk of heat-scalded sprouts. Standardized seeding depth and plant spacing ensure even field emergence, drastically reducing weak seedlings and missing plants. Harvested potatoes grow in uniform sizes, raising the proportion of marketable tubers.
2 Superior Mulch Sealing, Water Retention & Weed Suppression, Lower Agricultural Inputs
Only tiny holes remain at seeding points, which are immediately sealed with soil after planting. The fully intact mulch minimizes soil water evaporation for outstanding drought resistance. Weeds can barely break through the film, reducing herbicide usage and meeting eco-friendly green planting standards.
3 Stable Seeding Precision, Low Missing & Double Seeding Rate
Ground wheels drive synchronized chain transmission for smooth duckbill opening and closing. The machine works well with whole seed tubers and disinfected cut seed pieces. Four switchable plant spacings and consistent seeding depth eliminate manual thinning, reduce seed waste and cut tuber costs.
4 Integrated Drip Tape Compatibility, Ideal for Arid Potato Production Zones
Ridge forming, drip tape laying and mulching are finished in one go, placing irrigation lines right above the planting layer to boost water and fertilizer absorption efficiency. It performs excellently in drought and semi-arid potato growing regions including Gansu, Inner Mongolia, Northeast and North China, delivering stable yield improvements over long-term use.
5 All-in-One Composite Functions, Full Procedures Completed in One Field Pass
Fertilization, ridge forming, drip tape laying, mulching, seeding and soil backfilling are completed simultaneously. Tractors only enter the field once, avoiding repeated soil compaction. It saves fuel consumption and working hours, lowering overall planting costs significantly.
Applicable Scenarios & Operation & Maintenance Guidelines
Suitable Operators & Land Conditions
- Target users: Large-scale planting bases, professional potato cooperatives and large family farms
- Adaptable soil types: Loamy and sandy loam soils deliver optimal performance. Heavier clay soils require deep pre-tillage to prevent duckbill clogging from sticky mud.
- Compatible planting mode: National standard single-ridge double-row plastic mulch potato cultivation
Key Field Operation Tips
- Adjust the central pull rod before field work to calibrate seeding depth to 10–12 cm in line with local agronomic standards.
- Fine-tune the height of backfill shovels to fully seal seeding holes and prevent air leakage and weed growth.
- Keep the tractor running at a steady low speed; fast travel causes uneven punching depth and inconsistent plant spacing.
- Clean mud and tuber residue inside duckbills after daily operation to avoid jams and missing seeding.
- Set proper mulch tension: Over-tight film tears easily, while loose film cannot fit ridges closely and weakens water retention and weed control effects.
