In addition, the mean flowering time (MFT) and flowering speed (FS) were investigated according to the flowering period, and the calculation formula is as follows. Here, ti is the number of irradiation days after flowering, ni is the number of flowers on the day of irradiation, and N is...
The particle passage rate formula and the particle following the formula can be used to analyze the particle passing through the flow channel and the ability of the particles to follow the liquid and to evaluate the clogging resistance of the drip irrigation emitter flow channel. The specific for...
If the nitrogen content in the ith meshing is Mi, the calculation formula of the probability measure pi(ε) of the meshing is as follows: pi(ε)=Mi∑ni=1Mipi(ε)=Mi∑i=1nMi (2) where ε is the grid scale, n is the number of grids at the scale, and Mi is the measured ...
The C7–C30 alkane series was injected into the device using the determined method, and the RI calculation was performed. Peaks were defined in the FFNSC (natural and synthetic flavor and fragrance components) library to determine the peaks. The volatile aroma components in capia pepper samples ...
Its calculation formula is [45]: 𝑅𝑅=𝑋𝑒/𝑋𝑐RR=Xe/Xc (1) Taking cotton yield as an example, 𝑋𝑒Xe is the average yield of cotton under deficit irrigation (kg·ha−1); 𝑋𝑐Xc is the average yield of cotton under full irrigation (kg·ha−1). 𝐿𝑛𝑅...
