The cultivation methods and precautions of Lai grapes

1. Maintenance methods

1. Temperature: When Lai grape seeds germinate, a relatively high temperature is required for the seeds to germinate. This temperature range is between 30 degrees and 35 degrees. During the seedling stage, the temperature should be controlled between 20 degrees and 25 degrees. Below 15 degrees, the growth rate of the plant will slow down. When the temperature is below 10 degrees, the plant will be stunted. The flowering temperature can be guaranteed to be around 20 degrees. When the temperature is 25 degrees, the fruit setting rate is the highest.

2. Watering: It needs a lot of water during its growing period, and the soil needs to be kept moist for a long time. The temperature in summer is relatively high, so it is best to water it every other day. During the non-growing period, water needs to be controlled, and watering it once or twice a week is sufficient.

3. Fertilization: Before planting, you need to mix the soil with base fertilizer. You can choose decomposed manure for base fertilizer. When applying topdressing, you should choose human and animal manure and urine. The frequency of fertilization is once a week. After the flowering period, in order to promote fruit growth, you can increase the fertilizer concentration. During the peak fruit-bearing period, you should use a comprehensive compound fertilizer.

4. Light: It is a long-day plant and is best able to receive full-day sunlight without the need for human adjustment.

2. Breeding techniques

1. Intertillage: Intertillage is required from the seedling stage. Generally, intertillage can be carried out after watering for planting and when the soil surface is no longer sticky. The second intertillage is carried out about ten days after the first intertillage. When tilling, pay attention to protecting new roots and it is best to till shallowly.

2. Weeding: In order to avoid weeds competing with plants for nutrients, weeding should be carried out frequently after successful planting. If you find diseased seedlings or seedlings that are growing poorly, remove them all and replace them later.

3. Problem Diagnosis

1. Disease: It is easy to be infected with powdery mildew. After infection, it needs to be sprayed with methyl thiophanate for treatment. It should be noted that the agent must be diluted before use on the plant. The plants cannot be picked within a week after spraying. They should be picked after one to ten days until the drug effect evaporates.

2. Pests: For it, aphids are the number one pest. If infected, it needs to be sprayed with omethoate. If not infected, it can also be sprayed with omethoate once every two weeks for prevention and control.

IV. Other issues

1. Edibility: It is edible. In addition to being edible, it can also be used as medicine.

2. Toxicity: It is slightly toxic. Symptoms of poisoning include vomiting and nausea. Once discovered, hospitalization is required.
