Planting method of selenium-rich and calcium-rich grapefruit trees

Abstract

The invention discloses a planting method of selenium-rich and calcium-rich grapefruit trees. The planting method of the selenium-rich and calcium-rich grapefruit trees comprises the following steps of (1) seedling culture, (2) fertilizer applying, and (3) field management. The planting method of the selenium-rich and calcium-rich grapefruit trees has the beneficial effects that the grapefruit trees planted through the method can grow vigorously and are resistant to disease and high in pest resistance and stress resistance. Selenium-rich and calcium-rich grapefruits grown on the grapefruit trees are pure and natural in taste. The selenium-rich and calcium-rich grapefruits are rich in aftertaste and can leave a lingering fragrance in the mouth. Pulp is crisp and tender, and moisture is prevented from flowing outwards.

Description

technical field [0001] The invention belongs to the field of planting trees, in particular to a method for planting selenium-rich calcium pomelo trees. Background technique [0002] At present, we see various phenomena in the production process of farmers in rural areas. In order to avoid the pain of weeding, we use herbicides many times a year. In order to let the pests die quickly, we increase the dose of pesticides and increase the resistance of the pests. This creates a vicious circle, with a greater dosage of pesticides, and even high doses of poisonous pesticides are required when the crops mature. In order to pursue high yields and high benefits while being light, farmers seldom use the old farmyard manures, but use a lot of chemical fertilizers, resulting in herbicides in the soil. , Pesticide residues, and heavy metals generally exceed the standard. This is a common problem in China today. Therefore, the fish we eat now is not as sweet as it was in the 1960s, and t...

Problems solved by technology

[0002] At present, we see various phenomena in the production process of farmers in rural areas. In order to avoid the pain of weeding, we use herbicides many times a year. In order to let the pests die quickly, we increase the dose of pesticides and increase the resistance of the pests. This creates a vicious circle, with a greater dosage of pesticides, and even high doses of poisonous pesticides are required when the crops mature. In order to pursue high yields and high benefits while being light, farmers seldom use the old farmyard manures, but use a lot of chemical fertilizers, resulting in herbicides in the soil. , Pesticide residues, and heavy metals generally exceed the standard. This is a common problem in China today.

Therefore, the fish we eat now is not as sweet as it was in the 1960s, and the rice is not as fragrant as it used to be. Fruits also use a lot of hormones for high yield, so many fruits have lost their original taste.
