Method for cultivating selenium-rich grapes

Abstract

The invention belongs to the technical field of fruit plantation, and particularly relates to a method for cultivating selenium-rich grapes. The method mainly comprises the following steps: (1) soil preparation, and application of a base fertilizer; (2) nutritional water pouring; (3) application of a sprouting fertilizer, a selenium foliar fertilizer, a fruit setting fertilizer, a young fruit fertilizer and a fruit swelling fertilizer; (4) disease and pest control; and (5) harvesting. The application of the reasonably prepared fertilizers is combined with a reasonable fertilization way and a cultivation technology, so the effective utilization rate of the fertilizers is reduced, and the use amounts of the chemical fertilizer and a pesticide are reduced, thereby planted grapes are rich in organic selenium and other nutrients, and the quality and the yield of the product are improved. The base fertilizer is composed of a high temperature decomposed agricultural fertilizer, diammonium phosphate, urea, potassium sulfate, a calcium magnesium phosphate fertilizer and sodium selenite; and the selenium foliar fertilizer is composed of urea, calcium superphosphate, potassium sulfate, potassium dihydrogen phosphate, zinc sulfate, borax, a 1000 times dilution of amino acid chelated calcium zinc iron boron, a 800 times dilution of fruit calcium boron, a 300-600 times dilution of a bio-organic selenium fertilizer, and water.

Description

technical field [0001] The invention relates to the technical field of fruit planting, in particular to a cultivation method of selenium-enriched grapes. Background technique [0002] Grapes, also known as grapes, have always been welcomed by people. They are delicious, easy to eat, and fresh fruits with high nutritional value. Grapes can also be processed to make grape juice and raisins with high business value. Processing into wine. Grapes are not only delicious, but also have high nutritional value. The sugar content of grapes in ripe berries is as high as 10%-30%, mainly glucose. A variety of fruit acids in grapes are helpful for digestion. Eating more grapes properly can strengthen the stomach and stomach. Grapes contain minerals such as calcium, potassium, phosphorus, iron, vitamin B1, vitamin B2, vitamin B6, vitamin C, and vitamin P. beneficial. [0003] Humans began to cultivate grapes more than 2,000 years ago. It is currently the most widely distributed and cu...

Problems solved by technology

In recent years, the sales of fresh table grapes have been sluggish and profits have declined. The main reason is that the market is too concentrated, the quality of the fruit is poor, and the sales channels are lacking. Another important reason is the rapid increase in production costs.

Among them, chemical fertilizers and pesticides are important inputs. T...
