1. Land preparation and crop selection
Pea tips have shallow root systems and poor absorption capacity. The cultivation plot should have fertile soil, high organic matter content, strong fertilizer retention and water storage capacity, and neutral soil. Or slightly acidic sandy loam, loam, and clay are suitable for planting.
2. Seed soaking and germination
Select Taiwanese pea tip seeds with a germination rate of more than 98%, soak them in warm water at 55°C for about 2 hours, and then soak them in clean water at 20 to 25°C for another 10 seconds. Hours, change the water 2 to 3 times during this period, and always keep the water clean.
Drain the soaked pea seeds and place them in a constant temperature box at 32 to 35°C for germination. Wash the seeds with clean water at about 30°C every 8 hours. Generally, the germs will turn white after 24 hours and the seeds can be sown.
3. Sowing
Pea tips should be planted densely, with a row spacing of 20 cm and a plant spacing of 10 cm. 2 to 3 seeds are sown in each hole, and the seed amount per acre is about 10 kg.
4. Field management
During the seedling stage and time, pay attention to keeping the soil moist and weeding should be done in time before closing the rows. Due to the high sowing density, it is recommended to weed manually.
Keep the minimum temperature at night at 8 to 10°C, the optimal temperature during the day to be 15 to 20°C, the maximum temperature to be 28°C, and the soil moisture to be controlled at 75% to 85%.
Top dressing is mainly nitrogen fertilizer. Generally, 5 kilograms of urea per acre is applied once harvested, and potassium fertilizer is applied appropriately to improve plant disease resistance. Disposal of human waste is prohibited.
5. Harvesting
When harvesting, only the tender tips of the upper compound leaves of the plant (along with 1 to 2 unexpanded tender leaves) are picked. It is advisable to cut with a knife.
After the first harvest, it can be harvested again at an interval of 7 to 15 days, and 5 to 6 times can be harvested in one day. The picked tender tips are placed in the basket and should not be piled thickly to prevent them from heating up. Generally, about 400 kilograms of tender tips can be produced per acre.

Prevention and treatment methods of Fusarium oxysporum wilt disease in peas:
1. Basic methods
(1) Apply enzyme bacteria for retting Use prepared compost or fully decomposed organic fertilizer. Do not use incompletely decomposed soil fertilizer to improve the soil.
(2) Water properly and drain water promptly after rain to prevent excessive soil moisture. If necessary, perform cultivating to loosen the soil and create conditions for good root growth and development, so that peas can transform into disease resistance.
(3) Implement crop rotation. Pea root exudates will affect rhizobia activity and root growth of the plant in the following year, so continuous cropping is avoided.
2. Pharmaceutical methods
(1) Sow disease-free seeds. Use 0.3% of the seed weight of 70% thiophanate methyl or 50% carbendazim wettable powder plus 75% chlorothalonil wettable powder (1:1) to mix and dress the seeds and seal them for 48 to 72 hours before sowing, which can be postponed Onset lasts about 1 month.
(2) Start spraying 50% benomyl wettable powder 1500 times liquid or 40% polysulfide suspension or 50% carbendazim wettable powder 500 times liquid, 70% methyl Thiophanate wettable powder 500 times liquid, 75% chlorothalonil wettable powder 500 times liquid, 60% antifungal ultrafine powder 600 times liquid.
Once every 7 to 10 days, control 2 to 3 times continuously. Stop medication 7 days before harvest.
