Planting technology of virgin fruit

Soil preparation: the virgin fruit is not strict with the soil, ridging and ditching during soil preparation, and applying appropriate amount of farm manure. Sowing: can be carried out at the end of April, the seeds will be sterilized and put in a suitable temperature to promote germination, wait until the seeds appear white buds can be sown. Temperature: less than 15 ℃ will slow down, seedlings higher than 35 ℃ will burn out, and it will lead to flower and fruit drop at flowering and fruit stage. Fertilization: a total of 3 times of topdressing can be carried out at the seedling stage, flower and fruit stage and after the first harvest.

I. Land preparation

1. Virgin fruit is not very strict on soil, so it can be planted in general planting land, and ridging and ditching should be done during soil preparation, which is beneficial to drainage and irrigation in the later stage.

2. At the same time, an appropriate amount of rotten farm manure can be applied as base fertilizer to ensure the fertility of the soil and be beneficial to the healthy growth of virgin fruit.

Second, sowing seeds

1. You can choose to sow the seeds at the end of April. If you want to prolong the harvest time, you can also sow the seeds in advance. The seeds can be sterilized before sowing. The common method is to put the seeds in potassium permanganate solution and soak for about 10 minutes.

2. Then remove the seed and rinse it with clean water for several times. in order to improve its germination rate, it can be wrapped with cloth and placed at a suitable temperature to accelerate germination, and then the seeds can be sown when the seeds appear white buds.

Third, temperature

1. During the growth of the virgin fruit, the suitable temperature is about 20-28 ℃, during which the temperature should not be lower than 15 ℃, otherwise the growth of the virgin fruit will become slow, and the temperature should not exceed 35 ℃, because too high temperature will cause the seedlings to burn out.

2. Especially in the flowering and fruiting stage of virgin fruit, if the temperature is too high, it will lead to the phenomenon of falling flowers and fruit, which will reduce the quality and yield of virgin fruit, so it is necessary to adjust the appropriate temperature.

IV. Fertilization

The main results are as follows: 1. If the acidity of the planting land is strong, an appropriate amount of compound fertilizer can be applied, and if the planting land is alkaline soil, it is necessary to apply appropriate amount of calcium superphosphate. Virgin fruit generally needs to be fertilized three times during the whole growth period, the first time can be selected in the virgin fruit seedling stage, when the seedlings grow to 5-10cm.

2. When the virgin fruit blossoms and bears fruit for the second time, the main purpose of this stage is to improve the fruit setting rate, and the third time is to apply fertilizer after the first batch of virgin fruit is harvested, which is beneficial to promote the growth of new seedlings and accelerate the ripening of the second batch of fruit at the same time.

V. Prevention and control of diseases and insect pests

The main results are as follows: 1. During the growth period, there are few diseases and insect pests, and the common disease is easy to occur in the seedling stage, so in the seedling stage, an appropriate amount of dwarf can be sprayed to control.

2, the second is in the fruit flowering and fruiting period, this stage is prone to moths, during which you can go to the pesticide store to buy targeted pesticides for prevention and control.
