Detailed Explanation of Key Techniques for Growing Cape Gooseberry in Greenhouses
Cape gooseberry, also called goli or golden gooseberry, is an annual plant of the Solanaceae family. It has both medicinal and culinary uses and is a new type of premium nutritious health fruit. Cape gooseberry fruit contains multiple vitamins and other trace elements needed by the human body. It can be used to treat anemia and also has beauty-enhancing and anti-aging effects, as well as a certain preventive effect on cardiovascular and cerebrovascular diseases. So how do we grow cape gooseberry in greenhouses? Let's take a look below.
1. Site Selection and Land Preparation
Cape gooseberry is generally planted in flat brown loam soil with good drainage and irrigation conditions, sheltered from the wind, and facing away from the sun. The fertility of the planting site does not need to be too high; generally medium fertility is sufficient. Secondly, it must not be planted in soil where Solanaceae crops have previously been grown, as the disease incidence rate is extremely high. Prepare the land finely, break up the soil clods well, make the beds properly, and level the bed surface. The bed width is about 1.5 m, the height is 20 cm, the ditch width is 10 cm, the depth is 10 cm, and the ditches connect with one another.
2. Greenhouse Construction
For greenhouse cultivation of cape gooseberry, a greenhouse certainly needs to be built. After preparing the land, we build the greenhouse frame with a height of about 1.6 m, then cover the frame with double layers of transparent plastic to build the greenhouse, and then pile soil on both sides of the plastic and press it firmly so it will not be blown away by the wind. Once the basic greenhouse structure is complete, we need to leave a door for entering and exiting the greenhouse, as well as windows for ventilation, so as to ensure the normal growth of the cape gooseberry in the greenhouse.
3. Sowing and Seedling Raising
We need to set aside a plot inside the greenhouse for sowing and raising seedlings. For the seedling plot, we first water it thoroughly, then spread sufficient decomposed farmyard manure, mix the soil and manure evenly, then scatter the cape gooseberry seeds evenly on the seedling bed, gently pat the seeds into the soil with a rake, and cover them with a layer of rice straw, or use plastic film instead, to maintain soil moisture. After the cape gooseberry seedlings emerge, we must remove the rice straw or plastic film in time so as not to damage the seedlings.
4. Timely Planting Out
When the cape gooseberry seedlings grow to about 10 cm, we can transplant and plant them out. When pulling up the seedlings, we must be careful to keep the seedlings intact, especially the root system, and not damage the roots, which would affect the survival rate of the cape gooseberry seedlings. Secondly, it is advisable to carry along some of the base soil from the seedling plot, as this causes less damage to the roots and also allows the seedlings to adapt to the new environment more quickly after planting. When planting out, the surface soil temperature should generally reach at least 10 degrees or above, so timely planting out is also very important.
5. Field Management
About one week after the cape gooseberry is planted out, we should check the survival of the seedlings in the field, promptly pull out dead and weak seedlings, and replant to ensure a full stand of seedlings in the field. Secondly, cape gooseberry has the trait of tolerating poor soil, so when sufficient base fertilizer has been applied, later topdressing is also very simple. Generally, foliar fertilizer is sprayed only during the fruiting period, along with the use of phosphorus fertilizer and potassium fertilizer. Cape gooseberry is most averse to nitrogen fertilizer, so when growing cape gooseberry we must not use nitrogen fertilizer. It also has a certain drought resistance, so we only need to water it in moderation, but during the fruiting period the water requirement is relatively large, so the amount of water should be appropriately increased. Finally, pest and disease control must be done well, such as for white grubs, cutworms, and powdery mildew, which we can control with zinc phosethyl, phoxim emulsifiable concentrate, and chlorothalonil wettable powder respectively.
The above are the methods for growing cape gooseberry in greenhouses. Nowadays, greenhouse cultivation techniques are becoming more and more popular. Many crops, medicinal herbs, and others can all use greenhouses, and even the breeding industry can use greenhouse technology.
