Problems solved by technology

At present, selenium-enriched papaya is mostly produced by spraying selenium solution on the leaves or applying selenium fertilizer. The selenium solution is generally prepared by sodium selenite, and the timing of fertilization has not been well studied, resulting in the selenium content of papaya. not ideal

Embodiment 1

[0029] A planting method of selenium-enriched papaya, comprising the following steps:

[0030] (1) Site preparation and gardening: Select a sandy field with a soil layer thickness greater than 0.7 meters and neutral soil, and dig 0.8-1 meters long, 0.8-1 meters wide, and deep For a planting hole of 0.6-0.8 meters, put the excavated topsoil and subsoil aside, expose to the sun for 1 month and return to the hole, fill the lower part of the hole with the topsoil mixed with slow-release fertilizer, and fill the upper part of the hole with the subsoil mixed with decomposed organic fertilizer. Apply 8 kg of decomposed organic fertilizer and 3 kg of slow-release fertilizer to each hole; select 2-year-old papaya seedlings for planting in the planting hole, and pour enough clear manure water as rooting water; make a tree tray with a diameter of 50 cm and a height of 20-25 cm in the lower part of the papaya seedlings , and covered with straw;

Embodiment 2

[0039] A planting method of selenium-enriched papaya, comprising the following steps:

[0040] (1) Site preparation and gardening: Select a sandy field with a soil layer thickness greater than 0.7 meters and neutral soil, and dig 0.8-1 meters long, 0.8-1 meters wide, and deep For a planting hole of 0.6-0.8 meters, put the excavated topsoil and subsoil aside, expose to the sun for 1 month and return to the hole, fill the lower part of the hole with the topsoil mixed with slow-release fertilizer, and fill the upper part of the hole with the subsoil mixed with decomposed organic fertilizer. Apply 9 kg of decomposed organic fertilizer and 2.5 kg of slow-release fertilizer to each hole; select 3-year-old papaya seedlings to plant in the planting hole, and pour enough clear manure water as root-fixing water; make a tree with a diameter of 50 cm and a height of 20-25 cm in the lower part of the papaya seedlings plate and cover with straw;

Abstract

The invention provides a planting method of selenium-enriched papaya and belongs to the technical field of agricultural planting. The method includes the steps of firstly, preparing soil and building a garden, wherein decomposed organic fertilizer and slow-release fertilizer containing selenium are applied into planting holes during planting hole digging; secondly, performing root topdressing management; thirdly, performing foliar topdressing management, to be more specific, when the papaya starts fruiting, spraying selenium-enriched foliar fertilizer to papaya branches, leaves and fruits once every other 2-3 days; within 1-5 days when the green papaya becomes yellow, spraying selenium-enriched foliar fertilizer to the papaya branches, leaves and fruits once, and using the same method to spray the selenium-enriched foliar fertilizer to the papaya branches, leaves and fruits once after one day; fourthly, shaping and pruning; fifthly, controlling diseases and pests. The planting method has the advantages that the slow-release fertilizer containing selenium is applied before planting, the fertilizing timing of the selenium-enriched foliar fertilizer is controlled during papaya growth, formula and biological improvement is performed on the selenium-enriched foliar fertilizer, and the high-selenium-content papaya can be obtained.

Description

[0001] 【Technical field】 [0002] The invention relates to the technical field of planting, in particular to a planting method of selenium-enriched papaya. [0003] 【Background technique】 [0004] Selenium is an indispensable trace element in the human body. Both selenium and vitamin E are anti-peroxidation substances (peroxides are harmful to the human body). Resistance. The main manifestations of selenium deficiency in the human body are hair loss and nail loss. Some patients have skin symptoms, and a small number of patients may have neurological symptoms and tooth damage. People with mild or moderate selenium deficiency have no obvious signs or symptoms. Possible diseases caused by selenium deficiency in human body: energy deficiency malnutrition, hemolytic anemia, Keshan disease, Kashin-Beck disease, hypertension, ischemic heart disease, liver cirrhosis, pancreatitis, fibroid, cancer, fibroid, infertility disease, diabetes, cataract, etc. The World Health Organization ...
