High-yield cultivation methods of Solanum nigrum

Solanum nigrum is an annual plant, bearing black round fruit, the whole plant can be used as medicine, including fruit. Belongs to succulent berries. The wild growth range is wide and easy to grow. Across the temperate zone to the tropics. Solanum nigrum is good and easy to survive, so it is very suitable for artificial cultivation. However, if we want to have high yield and high yield, cultivation still needs to pay attention to some methods and techniques. We can't let it go. You can learn about these specific methods right away.

1. Planting density

Generally, it is necessary to plant sparse plants without wasting soil resources, not tight, high temperature and rain in summer, inconvenient drainage, relatively large air humidity, aggravating diseases in closed spaces, tight plants, artificial farming operations, easy to hurt plants, or cause plant contact and spread diseases. Generally, about 3000 seedlings are planted per mu. About one plant per hole, the row spacing is 30 cm, the plant spacing is 30 cm.

2. Weeding between seedlings

After the seedlings are unearthed, when there are three leaves, there will be crowding. At this time, the seedlings must be thinned out, weak seedlings, and a few diseased seedlings. Leave strong seedlings to maintain the remaining growth, during the seedling period, pay attention to pull out the nearby weeds, the weeds between the rows should also be removed. Prevent weeds from growing up and clogging the rows.

3. Topping

Topping, Wuming County trunk plant, the main branch grows to enough length, topping, promoting lateral branches, lateral branches grow to a certain extent and topping, so as to promote the full branches of the whole tree. In this way, when the tender shoots grow, pick more tender shoots. The tender shoots can be picked and eaten many times. Every time the lateral branches should be fertilized in time to ensure nutrition. The number of lateral branches determines the yield.

4. Topdressing and watering

Generally harvest a tender shoot on a fertilizer to supplement nutrition, the use of quick-acting chemical fertilizer, can quickly supplement nutrition, generally about 30 jin of nitrogen fertilizer urea, compound fertilizer 35 jin, there is time to spray potassium dihydrogen phosphate and so on. Maintaining the nutrition and taste of the leaves will be much better and improve the resistance of the plants.

5. Picking

Since the tender shoots are mainly picked during the growth period, pay attention to the picking nodes, do not hurt the stems and leaves, reduce the damage to a minimum and recover as soon as possible. Only pick the first section under the tender tip, don't pick too much, pick gently, don't pull hard. Don't hurt the plant.

This kind of picking method of Solanum nigrum determines that it is necessary to top fertilizer many times in the process of planting, maintain nutrition, maintain tree potential, and prolong picking time. And then
