How to grow rambutan planting techniques and matters needing attention

Rambutan is a fruit that must be no stranger to everyone. It is a tropical fruit with a very beautiful appearance and a bit of resemblance to litchi. Rambutan is a kind of fruit that people like very much because of its high nutritional value and edible value. However, because rambutan is a tropical fruit, its distribution in China is relatively small, and there are relatively certain requirements for planting.

How to grow rambutan

1. Seed selection: at this time, rambutan harvested the first batch of red ripe fruit, and the seeds left after eating the pulp were used to sow seeds.

2. Seed washing: wash the seeds after seed selection, that is, scrub the sugar on the seeds manually in clean water.

3. Make a sand bed: the sand bed is built on the land in front of the house and behind the house. It is better to have shade. Coarse river sand should be chosen because it is conducive to sprouting.

4. Germination: seed germination can be carried out on both sunny and rainy days. The bud eyes are facing down, put them on the sand bed and press them tightly. In this way, it is convenient to sprout and sprout quickly.

5. Sand bed management: the budding time is about 15-20 days. During this period, always keep the sand bed moist, too dry and wet is not conducive to germination, sunny days, 1-2 times a day, once in the morning and once in the evening. The moisture shall prevail. Pay attention to drainage on rainy days to avoid rotten seeds.

Planting techniques and matters needing attention of rambutan

I. planting techniques

1. Temperature

It likes the mountain environment with high temperature and humidity, no wind damage and low altitude. The annual average temperature is above 24 degrees Celsius, and the coldest month temperature is higher than 17 degrees Celsius, which is suitable for the growth and development of rambutan. Rambutan is not tolerant to drought at seedling stage, so it is necessary to increase water management properly. Water is most needed during the fruit growth period. Therefore, the annual rainfall of the cultivated land is required to be more than 1800 mm.

2. Soil

It is better to have a deep soil layer, rich in organic matter, loose fertility, good drainage and ventilation. The pH value of soil is between 4.5 and 6.5. Alluvial soil is the best, alluvial soil refers to the soil developed on river alluvium, generally, the soil formation time is short, the development level is not obvious, and the soil fertility is higher.

3. Water and fertilizer

In the first month after transplanting buds, water should be drenched regularly once a day, in order to be moist, and water should be drenched when the soil is dry. In the second month, the seedling pulled out the first new leaf, weeded the nutrition bag and loosened the soil between the rows. Prevent root damage when weeding. Water and fertilizer are applied thinly once a month.

II. Points for attention

The leaves of rambutan were mainly damaged by poisonous moths in the seedling stage. If the number of insects is small, it is best to kill them manually. If the hazard area is large, 38% methylvitamin salt can be selected. The liquid of octane EC is 800-1500 times, which can be used as an insecticide and can be effectively sprayed once.

How to reproduce rambutan

Rambutan generally has two methods of asexual reproduction and seed reproduction. Comparatively speaking, the result of seed reproduction is relatively late, and the quality is uneven and the quality is quite different. In addition, its real trees belong to dioecious fruit trees, of which males account for 34.2%, which is very disadvantageous to the regionalization of improved varieties of fruit trees. So we usually use aerial striping and grafting in asexual reproduction.

The difference between rambutan and litchi

1. Appearance

There are many red hairs on its shell, so it is called rambutan and enjoys the reputation of king of tropical fruits.
