Embodiment 1
[0035] This embodiment provides a planting management method for increasing the selenium content of white tea, planting white tea from scratch, and carrying out reasonable planting management, the specific process is as follows:
[0036] Step 1. Increase selenium in arable land: choose a soil depth of 70cm, ventilate to the sun, and land close to the water source as a white tea plantation. Selenium agent 2000kg, finely crushed and leveled the surface, drained overnight after pouring enough water, and covered with plastic film for the winter;
[0037] In March of the next spring, remove the film, plow the surface 50cm deep again, remove weeds and tree roots, and ventilate naturally for 3 days, spray the surface with a 500-fold dilution of baking soda with a concentration of 50%, and plow once every spraying The ground surface is 30cm, until the average soil pH value is 7.1, apply 500kg of compound plant ash per mu, finely crush and level the ground surface, and open planting di...
Embodiment 2
[0050] In this embodiment, the white tea that has been mined is selected as the management object, and the white tea tree is planted and managed by increasing selenium with water and fertilizer and increasing selenium with gas. The purpose is to increase the selenium content in the white tea; the specific process is as follows:
[0051] The first step, water and fertilizer to increase selenium: In the third year after the tea leaves are planted and survived, the white tea leaves are picked for the first time in mid-March. On the evening of the 5th day before picking, the white tea leaves are sprayed with selenium-enriched leaf fertilizer, and the tea leaves are selected when spraying. Spray on the back side of the tea leaves until the tea leaves are moist but not dripping; spray selenium-enriched foliage fertilizer once in March and September every year in the year of picking and after picking in the same way;
[0052] The second step, gas selenium increase: apply selenium-enri...
Embodiment 3
[0061] In this embodiment, the white tea that has been mined is selected as the management object, and the white tea tree is planted and managed only by water and fertilizer to increase selenium, the purpose is to increase the selenium content in the white tea; the specific process is as follows:
[0062] Water and fertilizer to increase selenium: In the second year after the tea leaves are planted and survived, white tea leaves are picked for the first time in late March. On the evening of the 5th day before picking, spray selenium-enriched leaf fertilizer on the white tea leaves. When spraying, choose the backside of the tea leaves as the Spray the target, spray until the tea leaves are moist but not dripping; spray selenium-enriched foliar fertilizer once in March and September every year in the year of picking and after picking in the same way;
[0063] And from the year when the tea leaves were picked, in January of each year, use 500 times dilution of baking soda with a c...
