To test the performance parameters and efficiency of the plastic greenhouse cleaning machine, an experimental facility for plastic greenhouse cleaning machine is designed specially.

Water pollution load of saliferous soil washed by water in plastic greenhouse;

Water-gathering and water-saving cultivation techniques in plastic greenhouse in the massif area;

Effect of diagonal bracings in the sidewall of plastic greenhouse frames on longitudinal stiffness;

Design of a simple and easy plastic shed in agricultural demonstrable area of Shalang in Kunming;

Automatic control of heat supply system in plastic sheds in winter;

The shape, material and structure dimensions of plastic shed used for growing seedlings was designed.

Different chemicals were used for treating seeds of Tilia amurensis in seedling-raising trial that made in a plastic house.

Illuminance changes inside and outside the plastic house share extreme similarities except that the former is lower than the latter.
