How much is snow pea per jin? High-efficiency off-season cultivation and management techniques

Snow pea, also called he ren dou, hui hui dou, etc., is one of the common vegetables. In recent years, snow pea has become very popular in the market because of its sweet and delicious taste, tender and fresh texture, and rich nutrition. So how much is the price of snow pea per jin? What are the key points of high-efficiency off-season cultivation and management techniques?

1. How much is the price of snow pea per jin?

The price of snow pea fluctuates considerably, especially during the off-season, when the price can reach over ten yuan; normally it is around 4-8 yuan. The specific unit price is subject to the actual market price.

1. Planting seasons for snow pea

For early spring solar greenhouse cultivation, sow from late January to early February and harvest from late April to mid-June.

For early spring plastic tunnel cultivation, sow from late February to early March and harvest from early to mid-May to mid-to-late June.

For spring open-field cultivation, sow from mid-to-late March and harvest from mid-May to late June.

For autumn delayed cultivation in a solar greenhouse, sow in late July and harvest from mid-October to mid-December.

For autumn delayed cultivation in a plastic tunnel, sow in early August and harvest from mid-October to mid-November.

For autumn open-field cultivation, sow in mid-to-late October and harvest from mid-to-late April to late May of the following year.

2. Key points of high-efficiency off-season cultivation and management techniques for snow pea

(1) Sowing time

The sowing period is a key factor affecting whether off-season snow pea cultivation succeeds. Sowing too early means higher temperatures, which inhibit seedling emergence and seedling growth; sowing too late delays the growth period, and the arrival of freezing weather leads to reduced yield. At the same time, because early-market prices are relatively high, under the premise that relevant conditions permit, the earlier the sowing, the higher the output value. According to the geographical location of the region and taking price factors into consideration, for areas at an altitude of 400-500 m, August 1-10 is the best period for sowing off-season snow pea; for areas at an altitude of 500-600 m, sowing can be carried out from July 25 to August 4; for areas above 600 m altitude, sowing can be advanced to July 20. The sowing rate is 3-4 kg/667 sq m, with a single row planted per bed. When sowing, open a shallow furrow 2-3 cm deep in the center of the bed, with one hole every 8-10 cm, sow 3 seeds per hole, and after sowing cover with 1-2 cm of fine soil.

(2) Scientific topdressing

During the seedling stage of snow pea, because rhizobia have not yet appeared, a small amount of nitrogen fertilizer should be applied before growth to accelerate early branching of the plants, increase the number of flowers and pod setting, and improve economic benefits. After all seedlings have emerged, carry out topdressing 3-4 d later, mixing 2.5 kg/667 sq m of urea with 1000 kg of water and sprinkling it; 24 d after sowing, mix 5 kg/667 sq m of compound fertilizer with 1200 kg of water and sprinkle it. It is worth noting that fertilizer must not be sprayed on the bean seedlings, to avoid affecting seedling growth. One month after sowing, during intertillage and hilling, mix 10 kg/667 sq m of 45% Norwegian compound fertilizer, 10 kg/667 sq m of superphosphate, and 5 kg/667 sq m of potassium chloride, then pour the mixture into the furrow. After 61 d from sowing, during the second intertillage and hilling, mix 10 kg/667 sq m of 45% Norwegian compound fertilizer, 10 kg/667 sq m of superphosphate, and 5 kg/667 sq m of potassium chloride, then pour the mixture into the furrow. After flowering and pod setting, fertilize once every 8 d, mixing 5 kg/667 sq m of 45% Norwegian compound fertilizer with 1200 kg of water and sprinkling it, for a total of 3 additional fertilizations. In addition, carry out root-zone topdressing once every week, using 0.2% potassium dihydrogen phosphate solution or 0.2% Yunda 120. Spraying foliar fertilizer can accelerate root growth, invigorate the bean seedlings, make the pods bright green, and give strong disease resistance and high yield.

(3) Pest and disease control

Off-season snow pea has relatively many pests and diseases. In the seedling stage, besides basal rot, there are also powdery mildew, brown spot, gray mold, cabbage caterpillar, aphids, leafminer, etc. Use 600-fold dilution of 2.5% Caixi or 2500-fold dilution of 5% Regent to control cabbage caterpillar; use 1500-fold dilution of 15% triadimefon to control powdery mildew and rust; use 600-fold dilution of 75% chlorothalonil to control brown spot; use 1000-fold dilution of 48% Lorsban emulsifiable concentrate to control leafminer; use 2500-fold dilution of 10% imidacloprid to control aphids. Control once every week, applying continuously 3 times. At the same time, pay attention to rodent control, and do not use highly toxic pesticides such as carbofuran and methamidophos.

For off-season snow pea, the main control target is bean stem maggot. From the emergence of bean seedlings until the seedlings grow to 30 cm, spray neem emulsion oil once every 3 d, which can solve the damage problem of bean stem maggot. If cotton bollworm, etc. are present, emamectin benzoate can be added at the same time for control.
