High-yield cultivation technology of black balsam pear

It is a new type of bitter gourd introduced from Taiwan in recent years. It is a dark green bitter gourd, but because it is close to black, it is called black bitter gourd. Its original name is Cuifei bitter gourd. The production period of black balsam pear is very long, and the quality is also very good. It is rich in nutrients, including vitamin content *. So is there any difference between the cultivation method of black balsam pear and balsam pear? How to grow it? So let's learn together.

1. Soil and fertilizer work

Because black bitter gourd was introduced from Taiwan, and the climate throughout the year in Taiwan is relatively warm, black bitter gourd * is suitable for growing in a warmer climate. However, black bitter gourd is very resistant to stress and has the characteristics of tolerance to fertilizers and barrenness. Therefore, the planting site should choose cohesive loam or sandy loam with sufficient soil fertility. It is not suitable to plant in the field where the previous crops are fruits. Tidy and level the ground, spread ample base fertilizer, turn into the ground and mix well.

2. Seedbed nursery

Black balsam pears are usually planted in February or October to November of each year. But when planting, you need to build a seedbed. After the seedbed is set, water it through, and then sprinkle the seeds evenly on the seedbed. Use a rake to gently press the seeds into the soil, and then cover it with a layer of straw and film Or, it is possible to build a greenhouse directly for greenhouse seedling cultivation.

3.Transplantation

When the black bitter gourd seedlings grow to about six to ten centimeters, they can be transplanted into the field. The suitable time for planting is generally April in each year, which means that the nursery time is generally about one and a half months. Planting is generally about 1,600 plants per acre, which means that the row spacing is about 1.2 meters, and the plant spacing is about 50 cm. If it is a late-maturing variety, it is generally planted according to about 550 plants per mu, and the maximum number cannot exceed 600.

4. Field management

After planting, you can't water immediately. Generally, you need to wait for three days before watering, and there is no rainfall, but when the temperature is high. The growth period of black bitter gourd is relatively common, and the harvest time is about three months, so we need to adjust the moisture in the field. We need to carry out reasonable watering according to the water demand of different growing seasons of black balsam pear, and at the same time we need to drain water in a timely manner. Because black bitter gourd is resistant to fertilizer, the amount of fertilizer required is relatively large. We must topdress scientifically to ensure the output and quality of black bitter gourd. When the black bitter gourd seedling grows to thirty centimeters high, it is necessary to set up a stand and pull the seedling to climb up and grow directly. Also, when the seedlings grow to about 60 cm, we need to pruning and pruning to promote the growth of side branches and increase the yield of black bitter gourd.
