Abstract: In order to quantitatively assess the objective impact of light, heat and water agricultural climate resources on food crops during summer drought, this paper uses the assessment methods for light and temperature potential productivity, and light, temperature and water potential productivity of food crops, performs the comparative analysis of the difference between the food production potential and the average climate state during summer drought, and objectively analyzes the strengths and weaknesses of agricultural climate resources in Guizhou Province during summer drought. Studies show that under summer drought in Guizhou Province, the light and temperature potential productivity of rice and corn is generally about 10% higher than in normal climate years, and the strengths of light and heat resources are obvious; the light, temperature and water potential productivity of rice and corn is generally 30% to 40% lower than in normal climate years, and the weaknesses of water resources hamper the crop growth. Rational development and efficient use of water resources and good light and heat conditions for crops during drought, are more conducive to agricultural production.
