Dutch beans planting management technology points
1. Planting time

Dutch beans are usually planted in winter, mainly in late October to mid-November. Sowed at this time, it can be harvested in April-May of the following year. Dutch beans are not good for its growth whether it is sown too early or too late. Sowing too early tends to make it grow vigorously before winter and freeze during cold snaps. Sowing too late will make its root system undeveloped and low yield the next year.

2. Selection of land preparation

Holland beans are adaptable, the soil requirements are not high, pay attention to the pH value on it. In acidic soil can not be planted, accordingly to choose the right land, and then timely deep plowing, improve soil porosity and permeability, applying sufficient base fertilizer. Font to choose the right good varieties of Dutch beans, the day before planting the seeds soaked in water for eight to twelve hours. Then dry them in the sun, plant one seed every 20 centimeters by sowing, then mulch and water. Keep the temperature between 10 and 18 degrees Celsius. You will usually see the seeds germinate in three to five days. After germination, if you feel that the planting is too dense, you can also inter-seed so that each seedling is spaced at 20cm or more.

3. Selection of seedling

Before sowing, apply 2500 grams of organic fertilizer, 20 kilograms of urea and 40 kilograms of potassium sulfate per mu. If the late growth is good and the planting density is high, you can moderately chase fertilizer two to three times, which can be carried out when it draws the tips and pods. In addition, at different stages of its growth, different fertilizers are needed, mainly phosphorus and potassium fertilizer and nitrogen fertilizer. Fertilizer needs to be adjusted in time to supplement nutrients according to its growth.

4. Fertilization methods

The Dutch beans need a lot of water throughout the growth period, only an adequate supply of water can make its growth vigorous. However, if overwatering occurs, the problem of root rot and seed rot can occur. So be careful to control the moisture, the time and amount of watering can be controlled. Whether to water or not can be determined by soil moisture. It should be noted that there is no need to water Dutch beans before germination.
