Embodiment 1

[0011] Embodiment 1: Topdressing is applied to soil in three times. When flue-cured tobacco is transplanted for the first time, topdressing formula N:P:K=1:0.6:0.5, 0.5kg / mu in terms of N fertilizer, diluted with water 100 times as a fixed Root water application; the second time is 20-25 days after flue-cured tobacco transplanting, topdressing formula N:P:K=1:1.4:1.4, calculated as N fertilizer 1.2kg / mu, diluted 5-10 times with water Apply the soil at 10cm of the flue-cured tobacco; the third time is when the flue-cured tobacco is peeled off the film, the topdressing formula N:P:K=1:0.3:3.5, calculated as N fertilizer 1.3kg / mu, diluted with water 5 to 10 times and then applied Apply the soil at 10cm from the flue-cured tobacco.

Embodiment 2

[0012] Embodiment 2: the topdressing fertilizer is applied to the soil three times, and when flue-cured tobacco is transplanted for the first time, the topdressing fertilizer formula N:P:K=1:0.6:0.5, 0.5kg / mu in terms of N fertilizer, diluted with water 100 times as a fixed Root water application; the second time is 20-25 days after flue-cured tobacco is transplanted, top dressing formula N:P:K=1:1.4:1.4, 1.2kg / mu in terms of N fertilizer, and add chelated trace element fertilizer at the same time (Sodium octaborate tetrahydrate 85g / mu, EDTA-zinc 200g / mu, EDTA-copper 120g / mu), diluted with water 5 to 10 times and applied to the soil at a distance of 10cm from the flue-cured tobacco; At the same time, the formula of topdressing fertilizer is N:P:K=1:0.3:3.5, 1.3kg / mu is calculated as N fertilizer, diluted with water 5 to 10 times, and applied to the soil 10cm away from the flue-cured tobacco.

Abstract

The invention discloses a topdressing method of a water soluble root fertilizer of flue-cured tobacco. Additional fertilizer is applied to soil in three times. The additional fertilizer is applied to soil for the first time when the flue-cured tobacco is transplanted, the additional fertilizer is prepared from N, P and K according to the proportion of 1: 0.6: 0.5, 0.5 kg of N fertilizer is applied to each mu of soil, and the additional fertilizer is applied as root setting water after being diluted for 100 times. The additional fertilizer is applied to soil for the second time 20-25 days after the flue-cured tobacco is transplanted, the additional fertilizer is prepared from N, P and K according to the proportion of 1: 1.4: 1.4, 1.2 kg of N fertilizer is applied to each mu of soil, and the additional fertilizer is applied to soil at the position 10 cm away from the flue-cured tobacco after being diluted for 5-10 times. The additional fertilizer is applied to soil for the third time after a membrane of the flue-cure tobacco is removed, the flue-cured tobacco is earthed up, the additional fertilizer is prepared from N, P and K according to the proportion of 1: 0.3: 3.5, 1.3 kg of N fertilizer is applied to each mu of soil, and the additional fertilizer is applied to soil at the position 10 cm away from the flue-cured tobacco after being diluted for 5-10 times. Compared with a conventional fertilizer application method, topdressing is performed with the method, the accumulation amount of dry matter of the flue-cured tobacco is increased by 6.74%, the yield and the production value of tobacco leaves are increased by 5.08% and 6.66% respectively, the potassium content of upper tobacco leaves is increased by 25.35% after treatment, and the smoking quality of the upper and middle tobacco leaves is remarkably improved.

Description

technical field [0001] The invention relates to a fertilization method for flue-cured tobacco. Background technique [0002] Water-soluble fertilizer (Water Soluble Fertilizer, referred to as WSF), is a multi-component compound fertilizer that can be completely dissolved in water. It can be quickly dissolved in water and easily absorbed by crops. Water-soluble fertilizers can contain all the nutrients needed for crop growth, and formulas can be designed according to the nutritional requirements of crop growth, which can effectively avoid fertilizer waste, and its fertilizer utilization rate is almost 2 to 3 times that of conventional compound fertilizers. In addition, water-soluble fertilizers are quick-acting fertilizers, which can quickly exert their fertilizer effects, and the fertilizer formula can be adjusted according to different growth conditions of crops at any time. The application method of water-soluble fertilizer is very simple. It can be irrigated with irrigat...
