1, grafted seedlings
Choose a "measuring ruler" with no pests and diseases, strong growth and full stem meat as the rootstock and graft it on sunny days. Cut the pitaya stem into a plane with a knife, insert the scion, align it with the cambium, and tie it tightly with cotton thread. Under the condition of 28-30℃, a large number of callus will be formed on the wound joint surface in 4-5 days, and the color of scion and rootstock is similar, indicating that the vascular bundles of them have healed and grafted successfully, and then they can be moved into the heel of seedbed to continue culture.
2. Seedling management
The seedbed should be a field with sunny ventilation, fertile soil and convenient irrigation and drainage. The whole bed should be carefully cultivated, with the border length of 2250px and 667 square meters of decomposed chicken manure or cow dung 1, 500-2,000 kg, and mixed rice husk ash 1, 000 kg, which should be fully stirred and applied to the seedbed during soil preparation. After that, calcium magnesium phosphate fertilizer 100- 150kg was applied, and it was fully stirred with a hoe, and the topsoil was applied to a depth of 4- 125px. Then sow seeds in the seedbed according to the row spacing of 75px, water them, and spray carbendazim 500 times 10 times every time.
3. 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.
4. Intercropping and artificial pollination: When planting pitaya, it is necessary to intercrop about 10% 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.
5. Pruning branches: After picking the fruit every year, cut off the bearing branches and let them send out new branches to ensure the yield in the coming year. Pitaya can be planted in various ways, such as climbing the wall or building a shed, but column cultivation is the most common, which has the advantages of low production cost and high land utilization rate.
Legend:
A poor Aztec woman lost her way in the desert, unable to call for help in pain, in a very dangerous situation, and went to another world in despair and illusion. ...
I heard a very clear and powerful voice coming from heaven! The voice told her to eat the plants next to her quickly! Eat the plants around you! She struggled to stretch out her hand to touch it, but she couldn't open her eyes. She just imagined that there were scattered and stretched rulers around her. There are few other plants in this particularly hot desert. She saw flashing red light in the illusion, dotted with pitaya between the scales measured, like handfuls of burning hunting, and her beating heart was shouting, inspiring her to stick to it! A breeze, millions of young beauties came running to her with huge lilies!
As if in a dream, her hand touched a blowing one, and she felt groups of swaying fairies and clusters of brilliant flowers changing alternately in front of her eyes, like a thick green ruler. When she magically pulled it, it broke, and her hand was stabbed with blood, but she didn't feel pain. She seemed to be guided by a magical force, mechanically biting this thick ruler and eating another one.
Just before noon, when the sun was more vicious, something magical happened! The Aztec woman woke up, her physical strength recovered quickly, her almost chapped lips became rosy like magic, and gradually covered her whole body like waves. She walked out of the desert smoothly!
The legend of pitaya has been passed down from generation to generation, and the rulers regard it as fairy grass. Pitaya, also known as fairy fruit and honey fruit, its branches, flowers, fruits and roots have become indispensable special crops for local people, with unique medicinal and edible functions. As a sacred symbol, pitaya is respected by the world, and this tradition later spread all over the world with the invasion and expansion of European colonialism. Pitaya is the first-class edible plant fruit for human beings, which symbolizes many beautiful ideals of human beings, such as good luck, health, wealth and longevity. Whether people are visiting relatives and friends or visiting patients, there must be a dragon fruit in the center of the fruit blue that they carry with them, which indicates many good wishes. No matter national leaders or ordinary people, dragon fruit is often inseparable from ancestor worship.
