Cultivation techniques of Hongxin pomelo

Red-heart pomelo is a new variety of pomelo. Red-heart pomelo is not used in white pomelo. Red-heart pomelo contains a natural pigment, resulting in red flesh. However, this pigment has a certain health care effect on the human body, and is beneficial to diseases such as cardiovascular and cerebrovascular diseases and kidney diseases. Red heart pomelo now has a very wide planting area in China, so how to cultivate red heart pomelo? The following editor brings you the cultivation techniques of red heart pomelo, let's have a look!

1. Land preparation and garden construction

The cultivation of Hongxin pomelo should choose the leeward slope with lower altitude, and require fertile soil, soft and deep soil, rich humus, sufficient light and normal drainage and irrigation. After selecting a good site, dig holes in the ground and dig deep into the soil to reduce the number of germs in the soil. The area of the planting hole should not be less than 1 square meter. If it is flat, make a bed at least 35 centimeters high, and then dig a ditch. And drive in together with the base fertilizer to ensure that there is sufficient farm manure in each planting hole, promote the nutrient absorption of young trees, ensure healthy growth, and reduce the incidence of diseases and insect pests.

2. Seedling management

After digging the planting hole, the planting density should be controlled in time. Usually Hongxin pomelo is first grafted and then planted, and about half a month after successful grafting, dung water is properly applied to ensure that it is once a month. Each pomelo tree is guaranteed to have a robust new shoot, cut off the extra shoots and erase the sprouts in time. Unbind in time after a month to promote the wound healing of the grafting site. During the grafting period, we should pay attention to regular watering to ensure that the soil is moist and prevent poor growth of young trees caused by lack of water. When the new shoots and stems are about 16 cm completely lignified, they can be planted.

3. Fertilizer and water management

The tree shape of red heart pomelo is large, the amount of flowers and fruits is relatively high, and the demand for nutrition is relatively large. Especially after Hongxin pomelo enters the fruiting stage, nutrition and reproductive growth are carried out together, and topdressing is needed for more than five times in the whole fruiting period. For example, for the first time in mid-March, the main topdressing fertilizers were compound fertilizer and urea, in order to promote the growth of new shoots and improve the flowering rate. Then, in the early fruiting period of mid-May, strong fruit fertilizer was applied, mainly farm manure. We should control the application of water and fertilizer according to the age of fruit trees, fruit yield, soil and other conditions to ensure to meet the water and fertilizer needs of Hongxin pomelo.

4. Pest control

The prevention and control of diseases and insect pests of red-heart pomelo is very important, which will cause harm to all organs of red-heart pomelo. As a result, the flowering and fruiting rate of pomelo is seriously affected, the planting benefit is low, resulting in reduced yield or even no yield and other consequences. The common diseases and insect pests of Hongxin pomelo are similar to those of citrus trees such as ordinary white pomelo, mainly for prevention. Disinfect the orchard regularly, strengthen the management of the orchard, often observe the orchard, and achieve early detection and treatment of diseases and insect pests. Promote the growth of red heart pomelo, strengthen the growth, improve the resistance and immunity of trees, and reduce the incidence of diseases and insect pests.

The above is a brief introduction to the cultivation techniques of Hongxin pomelo. The growth cycle of Hongxin pomelo is relatively long. When it enters the fruiting period, it can be harvested continuously for many years. However, we also need to do a good job in orchard management.
