Planting techniques of Shatian pomelo Control methods of Diseases and insect pests of Shatian Pomelo

It is time to eat a lot of grapefruit, and the efficacy of grapefruit is very many, and the taste is sweet and sour, so it is loved by many people in our life. Shatian pomelo is a very popular kind in life, and it is very good to eat it properly. But what is the planting technique of this fruit? Let's take a look at it together.

Planting techniques of Shatian pomelo

1. Garden construction: Shatian pomelo must choose places with deep, loose, fertile soil and sufficient water resources to build a garden. The mountain should choose a gentle slope with a slope of less than 20 degrees and a gentle slope from north to south, and there should be a water source forest at the top of the mountain.

2. Seedling cultivation: Shatian pomelo seedlings are cultivated by grafting, barging and cutting, but in production practice, grafted seedlings are superior to barged seedlings and cutting seedlings, so grafted seedlings are mostly propagated by grafting in production practice, and grapefruit seedlings are gradually eliminated by barging and cutting. In order to accelerate the propagation of seedlings and meet the needs of the development of Shatian pomelo production, small rootstock seedlings should be used for grafting as much as possible.

3. Planting techniques: the planting time of Shatian pomelo is usually spring planting (April-May) after spring shoot maturity and autumn planting after autumn shoot ripening. Before planting, the seedlings of the same class are graded, the overlong roots and overdense branches are cut off, 3-4 main branches are retained, and the roots are replanted with mud. When planting, the grafting interface should be exposed, the soil in the rhizosphere should be knocked fine, and the root group should be stretched in all directions. After covering the soil, lift the seedlings slightly upward and cover the fine soil firmly. After planting, it is necessary to pour enough water to set the roots, and sprinkle it once a day for the next 7 days to ensure survival, and insert windproof poles and cover grass.

4. Adult tree management: Shatian pomelo fruit trees have four main fertilization periods, namely, post-harvest fertilizer, pre-flowering fertilizer, stable fruit fertilizer and promoting shoot and strong fruit fertilizer. In addition, the need for fertilizer should be determined according to the amount of fruit hanging and tree potential of the plant.

Control methods of diseases and insect pests of Shatian pomelo

1. Scab

Scab mainly harms spring shoots and young fruits, the leaves begin to show oil-immersed spots, the disease spots expand, and protrude to one side into a conical tumor, like horn or funnel-shaped, rough surface.

Measures: select disease-free seedlings and soak scions and seedlings from non-disease-free nurseries or 50% carbendazim wettable powder for 30 minutes.

2. Brown rot Phytophthora

It mainly harms the fruit and causes a large number of fruit drop after being infected. In the early stage of the disease, light brown dots appeared on the pericarp, and showed dark brown waterlogging, and the spot became soft and slightly sunken.

Strengthen the management, remove the diseased fruit in time and disinfect the orchard with raw lime powder, pay attention to ditching to reduce stagnant water and prevent waterlogging, and properly prune to improve the ventilation and light transmission of the orchard. During the period of fruit growth and development, nitrogen, phosphorus and potassium combined with farm manure were applied to enhance the resistance.

What if Shatian pomelo only blossoms but doesn't bear fruit?

The reason why Shatian pomelo only blossoms but does not bear fruit is due to the lack of insect pollination and boron deficiency in soil. Artificial pollination can be carried out for lack of insect pollination, the best pollination time is 8-11:00 in sunny morning, followed by 4-7 pm, but the best method is to raise bees in Shatian pomelo orchard where pollination trees have been interplanted. For boron deficiency in the soil, lime or borax can be applied. It is worth noting that Shatian pomelo is on the shady branches in the crown, so these flowers should pay more attention to pollination.

Where is the origin of Shatian pomelo?

Shatian pomelo is a native product of Rong County, Guangxi Zhuang Autonomous region, because it was first planted in Shatian Village, Rong County, Guangxi, so it is called Shatian pomelo. It was exported to Hong Kong, Nanyang, Europe and America as early as the 1930s. Now it has been expanded to Xunjiang, Longjiang, Guijiang, Lijiang and Hongshui River basins in Guangxi. Guangdong, Hunan, Sichuan, Zhejiang and Jiangxi have also been introduced. Guangxi has become the largest concentrated producing area of Shatian pomelo in China in 2013. Shatian pomelo planting area in the autonomous region is hundreds of thousands of mu.

The planting technology of Shatian pomelo is introduced here first. I hope it will be helpful to everyone. The planting method of Shatian pomelo is not difficult, but it should be noted that it is necessary to increase the yield, which is very necessary for the control of diseases and insect pests.
