Longevity pea cultivation technology in Taiwan

Taiwan longevity peas, hard pod species, resistance to powdery mildew, plant type upright from life, dark green leaves, to harvest barley, eating green beans as the main purpose. The plant height is about 70-90 cm, most of them are single flowers and white flowers. British straight, blunt tail, dark green, alum length 9-10 cm, axillary width 1.4 cm, pod number of 6-10 tablets, particle size of 1 cm. Planting in Yunnan, from August to October in autumn, about 75-120 feet can be harvested. For high-yield cultivation, the number of single plants is about 20, and the yield of barley can reach 1200 kg, and about 50% of grains are produced. Fresh full grain, dark green grain, sweet and tender, very good merchandise. Marketed with picks or peels for cooked foods, quick-freezing or canning.
Planting environment

1. The soil has a wide adaptability. The most suitable soil is a loam (pH 6.5-7.5) with good ventilation.

2. Temperature optimum seedling temperature 8°C-12°C. The optimum temperature for flowering and sprouting is 1°C-20°C.

3. Temperature seedling, water control and protection; during the flowering stage, keep the soil moist (but not too wet).

4. Good light.

Planting density

15,000 per acre, ridging and trenching on demand. The ridge height is 10-15 centimeters. On the ridge surface, the ridge is furrowed and sowed on the ridge. The spacing is 60 centimeters. Seeds are planted at a spacing of 15 centimeters and 2 seeds are planted at each point.

Field management

1. Use 2,000 kg of rotten farmyard fertilizer as base fertilizer per acre before sowing.

2. Use 15 kg compound fertilizer (N:P:K = 10:10:10) per acre as seed fertilizer when planting, and apply by open trench. After sowing 3 days, if the lyrical condition is not enough to germinate, water should be used to promote seedlings.

3. When the seedling height is 20-30 cm, 10 kg of urea will be applied to the urea and shallow cultivating weeds will be used.

4. After flowering and poding, more than half of the plants bloom, cultivating and weeding the soil, spraying 0.2% potassium dihydrogen phosphate solution 2-3 times per acre to keep the soil moist (in case of waterlogging, the water should be drained immediately, and the water must be watered when drought occurs). Focus on controlling locusts.

Pest control

According to local conditions of pests and diseases, under the guidance of agricultural personnel to control. Among them, the wet environment is prone to cause root rot or rust. The flowering stage is vulnerable to locusts and leafflies. Special attention should be paid to early prevention and control.

Harvesting

About 20 days after the flower was cut, when the beans were obviously bulging and the pods were obviously broken, the barley continued to be harvested. The harvested barley should be placed in a cool and ventilated place and be listed or processed in time.

Precautions

1. Planting sweet peas requires sufficient amounts of phosphorus and potassium to promote branching and enhance resistance. For example, if the phosphate fertilizer is insufficient, the branching of the main stem at the base decreases, and the elongation of the plant is insufficient; if the potassium fertilizer is insufficient, the growth of the stem and the sweetness of the fresh product will be affected.

2. For the lack of farmyard fertilizer, plant fertilizer should be added as base fertilizer. If planting on acid soil, appropriate amount of lime should be used to correct the pH of the soil to make it suitable for planting.

3. Do not soak the seeds before sowing. The soil should not be too wet when sowing, otherwise it will cause bad seeds; the seeds must not be exposed to potash, otherwise it will reduce the emergence rate.

4. In the rainy season before the harvesting of green bark, the husk susceptibility lesions and the use of biological bactericide spray can effectively reduce the husk lesions and improve the appearance quality of barley.

5. High-yield cultivation, covering with a film can increase the temperature and ensure the quality of the crop.

6. Planting sweet peas cannot be continued.
