| 1、一膜4行 1. Four lines of one membrane 滴灌大豆用1.45米的膜，滴灌带一管2行。此种模式是借鉴棉花的大三膜12行的模式，株距9.5厘米，平均行距42.5厘米，最小密度是1.6万株/667米2。大豆株距是固定的，行距较宽，只能通过增加每穴留苗数达到较高密度，适宜于生长繁茂的中晚熟大豆品种。 1.45M film is used for drip irrigation of soybean, and one tube and two lines are used for drip irrigation. This model is based on the model of 12 lines of big three film of cotton. The plant spacing is 9.5cm, the average row spacing is 42.5cm, and the minimum density is 16000 plants / 667m2. The plant spacing of soybean is fixed and the row spacing is wide, which can only be achieved by increasing the number of seedlings left in each hole, which is suitable for the middle and late maturity soybean varieties with luxuriant growth. 2、一膜6行 2. Six lines of one membrane 滴灌大豆用2.05米的膜，滴灌带一管2行。此种模式是借鉴棉花的两膜12行模式，大豆株距9.5厘米，平均行距38.3厘米，最小密度是1.8万株/667米2。适宜于生长量大、生长势强的中熟及中晚熟大豆品种。 2.05m film is used for drip irrigation of soybean, and one tube and two lines are used for drip irrigation. This model is based on the two film 12 row model of cotton. The plant spacing of soybean is 9.5cm, the average row spacing is 38.3cm, and the minimum density is 18000 plants / 667m2. It is suitable for medium and late maturing soybean varieties with large growth and strong growth potential. 3、一膜8行 3. 8 lines of one membrane 滴灌大豆用2.05米的膜，滴灌带一管4行。此种模式是借鉴棉花的两膜12行模式，大豆株距9.5厘米，平均行距28.8厘米，很容易达到高密度，理论密度是2.44万株/667米2。适宜于抗倒伏性强的中晚熟品种、大部分的中熟品种及中早熟大豆品种。 Drip irrigation soybean with 2.05m film, drip irrigation with a tube of 4 lines. This model is based on the two film 12 row model of cotton. The plant spacing of soybean is 9.5cm, and the average row spacing is 28.8cm. It is easy to achieve high density. The theoretical density is 24400 plants / 667m2. It is suitable for middle late maturity varieties with strong lodging resistance, most middle maturity varieties and Middle Early Maturity soybean varieties. |
