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

[0026] A planting method of selenium-enriched papaya comprises the following steps:

[0027] (1) Harvest the papaya whose exocarp is blue-yellow on the fruit trees over 3 years old in August. Cut open the harvested fresh fruit, take out the seeds and dry them, and select the seeds with full grains.

[0028] (2) Before sowing seedlings, soak the seeds with a mixed solution of appropriate concentration of soda and sodium selenate for 10 hours, pick up and drain after soaking, then soak the air-dried sand with sodium selenate solution, and then mix the sand with the seeds. Mix it, then spread it in the seedbed according to the row spacing of 18 cm, and finally cover it with straw or plastic film to keep the humidity of the bed soil.

[0029] (3) After the seedlings are unearthed, spray them with Bordeaux solution once a week for 2 weeks; Trace amount of selenium-enriched bio-fertilizer is to be planted when the height of the seedling is more than lm; wherein, the weight concentr...

Embodiment 2

[0041] A planting method of selenium-enriched papaya comprises the following steps:

[0042] (1) In September, the papaya whose exocarp is blue-yellow on the fruit tree with a tree age of more than 3 years is harvested. The fresh fruit is cut open, the seeds are taken out and dried, and the seeds with full grains are selected.

[0043] (2) Before sowing seedlings, soak the seeds with a mixed solution of appropriate concentration of soda and sodium selenate for 12 hours, pick up and drain after soaking, then soak the air-dried sand with sodium selenate solution, and then mix the sand with the seeds Mix it, then spread it in the seedbed according to the row spacing of 18-20 cm, and finally cover it with straw or plastic film to maintain the humidity of the bed soil.

[0044] (3) After the seedlings are unearthed, spray with thiophanate-methyl solution once every 10 days, spray 3 times, and then cultivate the soil. When 3 leaves grow, promote the roots to penetrate deeply to prev...

Abstract

The invention relates to the technical field of crop planting, in particular to a planting method of selenium-rich papaw. Selenium-rich foliage fertilizer is sprayed in the fruiting period of papaw indifferent time periods repeatedly. During preparation of the selenium-rich foliage fertilizer, firstly, alfalfa, chicken manure, radix astragali dregs, furfural residues, dry pine needles, eggshells,brown sugar and a biological fermentation agent are mixed for fermentation. Through reasonable matching of fertilizer and the planting method, planted papaw has high survival rate and high growth quality. Papaw plants produce a lot of natural organic selenoprotein elements due to reasonable fertilization, and the method is simple, green, environmentally friendly and high in yield. Selenium components are easy to absorb during breeding, nutrition of the papaw is enriched, the purpose of selenium-rich papaw production can be achieved, the current situation of selenium deficiency can be relieved, and the method is applicable to large-scale planting.

Description

technical field [0001] The invention relates to the technical field of crop planting, in particular to a planting method of selenium-enriched papaya. Background technique [0002] Papaya is warm in nature and sweet and sour in taste. It can be eaten as a vegetable when it is immature; it can be eaten as a raw fruit when it is mature. The skin of papaya is smooth and beautiful, the flesh is thick and delicate, the aroma is rich, the juice is rich, sweet and delicious, and rich in nutrition. It is known as "the fruit of Baiyi", "the emperor of fruits" and "longevity melon". It is one of the four famous fruits in Lingnan . Papaya is rich in more than 17 kinds of amino acids, calcium, iron, etc., and also contains papain, papain, etc. Selenium is an essential trace element for the human body and participates in the synthesis of various selenium-containing enzymes and selenoproteins in the human body. In recent years, with the enhancement of people's awareness of health care a...
