Dutch beans, also known as lotus seed beans, return beans, etc., is one of the common vegetables. In recent years, Dutch beans are very popular in the market because of their sweet and delicious taste, tender flavor and rich nutrition. How much is the price of Dutch beans per jin? What are the key points of out-of-season efficient cultivation and management techniques?

How much is the price of Dutch beans per jin?

The price of Dutch beans changes greatly, especially in the off-season, the price is as high as ten yuan, usually about 4-8 yuan, the specific unit price is subject to the market site.

2. Off-season and efficient cultivation and management techniques of Dutch bean.

1. Dutch bean planting season

It was cultivated in solar greenhouse in early spring, sowed from late January to early February and harvested from late April to mid-June.

The greenhouse cultivation in early spring was sown from late February to early March and harvested from the first and middle of May to the middle and late June.

Spring open-field cultivation was sown in mid-late March and harvested from mid-May to late June.

Autumn cultivation in solar greenhouse was postponed for sowing in late July and harvested from mid-October to mid-December.

The delayed cultivation in autumn greenhouse was sown in early August and harvested from mid-October to mid-November.

The autumn open field was sown in mid-late October and harvested from mid-late April to late May the following year.

2. Key points of off-season and efficient cultivation and management techniques of Dutch bean.

(1) sowing time

Sowing date is the key factor affecting the success of out-of-season Dutch beans. Early sowing temperature inhibits seedling emergence and seedling growth. Sowing too late will delay the growth period, and the arrival of freezing will lead to a reduction in yield. At the same time, due to the high market price in the early stage, the earlier the sowing, the higher the output value under the premise of relevant conditions. According to the geographical location of the region and considering the price factors, the best time to sow anti-season Dutch beans is from August 1 to 10 at an altitude of 400m to 500m, and from July 25th to August 4th at an altitude of 50000m. Sowing can be carried out in areas higher than 600m above sea level to July 20th. Sowing rate 3~4kg/667m2, one row per row, a shallow trench deep in 2~3cm was opened in the middle of the border when sowing, and each hole in 8~10cm was sown with 3 seeds. After sowing, it was covered with fine soil of 1~2cm.

(2) Scientific topdressing

Because the rhizobium did not appear in the seedling stage of Dutch bean, a small amount of nitrogen fertilizer should be applied before growth to speed up the branching of plants as soon as possible, increase the number of flowers and pods, and improve economic benefits. Topdressing was carried out 3-4 days after all the seedlings were sent out, urea of 2.5kg/667m2 was mixed with water of 1000kg, and compound fertilizer of 5kg/667m2 and water of 1200kg were mixed and leached 24 days after sowing. It is worth noting that fertilizer should not be sprayed on the bean seedlings to avoid affecting the growth of the seedlings. One month after sowing, 45% of the Norwegian compound fertilizer of 10kg/667m2, calcium superphosphate of 10kg/667m2 and potassium chloride of 5kg/667m2 were mixed and poured into the ditch during the process of soil cultivation. 61 days after sowing, 45% Norwegian compound fertilizer of 10kg/667m2, calcium superphosphate of 10kg/667m2 and potassium chloride of 5kg/667m2 were mixed and poured into the ditch during the second cultivation. After flowering and podding, fertilizing once every 8 days, 45% of 5kg/667m2 Norwegian compound fertilizer was mixed with 1200kg water, and a total of 3 additional fertilizers were needed. In addition, extra-root topdressing was carried out every other week, with 0.2% potassium dihydrogen phosphate solution or 0.2% Yunda 120. Spraying foliar fertilizer can accelerate root growth, activate bean seedlings, bright green pods, strong disease resistance and high yield.

(3) Prevention and control of diseases and insect pests

There are many pests in off-season Dutch bean disease. in addition to basic rot, there are powdery mildew, brown spot, gray mold, cabbage insect, aphid, leaf miner and so on in seedling stage. Use 2.5% triadimefon or 5% fipronil of 2500 times to control cabbage worm, 15% triadimefon of 1500 times to control powdery mildew and rust, 75% chlorothalonil of 1000 times to control leaf miners, and 2500 times of imidacloprid to control aphids. Prevention and treatment was carried out once every one week, and the drug was used continuously for 3 times. At the same time, attention should be paid to the prevention and control of rodent damage, and high concentrations of toxic pesticides such as carbofuran and methamidophos should not be used.

Soybean stalk flies are mainly controlled in off-season Holland. During the period from soybean seedlings unearthed to 30cm, imipramine emulsified oil is sprayed every 3 days, which can solve the damage problem of bean stalk flies. For example, cotton bollworm can be controlled with methamidomectin benzoate at the same time.
