You can grow pitaya in Huichang, Ganzhou.

It is the thoroughfare of Jiangxi, Fujian and Guangdong. It is 56 kilometers wide from east to west and 85 kilometers long from north to south. It is 0/37 km away from Ganzhou/KLOC-(via Shanshupai and Ruigan Expressway) and 440km away from Nanchang, the provincial capital (via Ruijin and Fuzhou).

1. Dilute application of thin fertilizer: Due to the long fruit harvesting period, organic fertilizer should be applied again every year, and NPK compound fertilizer should be applied in a balanced way for a long time. Potassium and magnesium fertilizer should be supplemented during flowering and fruiting to promote sugar accumulation and improve fruit quality. Keep the soil moist during the fruiting period, and cover the tree tray with grass or mushroom residue. When the weather is dry, water should be poured every 3-4 days. Pitaya, like other cactus plants, is smaller than traditional fruit trees. Therefore, fertilization should be based on the principle of sufficient amount, small amount and multiple times.

Young trees (1-2 years old) mainly apply nitrogen fertilizer, so as to apply less frequently and promote the growth of trees. Adult trees (more than 3 years) are mainly applied with phosphorus and potassium fertilizer, and the amount of nitrogen fertilizer is controlled.

Fertilization should be carried out in the germination period of new shoots and the fruit expansion period in spring. Fertilizer is generally made of cake residue, chicken manure and pig manure according to the formula of 1: 2: 7, and 25 kilograms of organic fertilizer is applied to each plant every year. Or in July every year, 10 June, and in March of the following year, each plant is applied with cow dung compost 1.2 kg and compound fertilizer of 200 grams. The root system of pitaya is mainly distributed in topsoil, so fertilization should be adopted to avoid deep furrows to avoid root damage. In addition, after each batch of young fruits is formed, 0.3% magnesium sulfate +0.2% borax +0.3% potassium dihydrogen phosphate 1 time is sprayed outside the roots to improve the fruit quality.

Because of the long harvest period of pitaya, organic fertilizer should be applied again, and nitrogen, phosphorus and potassium compound fertilizer should be applied in a balanced way for a long time. Completely using fertilizers with too high nitrogen content in pig manure and chicken manure makes the branches thick, dark green, fragile, easy to break in strong wind, large and heavy fruits, poor quality, low sweetness and even sour or salty. Therefore, potassium fertilizer, magnesium fertilizer and bone meal should be added during flowering and fruiting to promote sugar accumulation and improve fruit quality.

There are many aerial roots of pitaya, which can be transformed into absorption roots. Expanding holes and improving soil can gradually broaden the distribution of root system; You can also induce aerial roots to go to the ground by binding and dragging. [9]

2. Picking: When the branches grow to 1.3- 1.4 meters long, the picking core promotes branching and makes the branches droop naturally.

3. Interplanting and artificial pollination: When planting pitaya, it is necessary to interplant about 10% of white pitaya. Cross-pollination among varieties can obviously improve the seed setting rate. In case of rainy weather, artificial pollination is needed. Pollination can be accomplished by brushing pollen directly on the stigma of female flowers before flowering at night or closing in the morning.
