Abstract:

To clarify the effects of climate change on the growth development and yield of maize in the system of maize intercropping peanut, we performed the planting pattern of two rows maize intercropping and four rows peanut. Field experiments were carried out with TC (ambient temperature and ambient CO2 concentration), +T+C (elevated temperature and elevated CO2 concentration) in 2018, and TC, +TC (elevated temperature and ambient CO2 concentration), and +T+C in 2019, with two phosphorus levels of P0 (P2O5 0 kg hm-2) and P180 (P2O5 180 kg hm-2), respectively. The effects of elevated temperature and CO2 concentration on growth, dry matter accumulation and distribution, photosynthesis and yield of intercropping maize were studied. Results were as follows: (1) Compared with TC, the numbers of days from emergence to silking, silking to maturity, and emergence to maturity of intercropping maize under +TC were shortened respective by 4, 2, and 6 days. Compared with +TC, the number of days from emergence to silking of intercropping maize under +T+C was shortened by three days, while the numbers of days from silking to maturity, and emergence to maturity were increased by five days and two days. Compared with TC, the number of days from emergence to silking, and emergence to maturity of intercropping maize under +T+C was shortened by 4-7 days and 2-4 days, respectively; and the number of days from emergence to maturity was extended by 1-4 days. (2) The leaf area, net photosynthetic rate, and leaf area duration of intercropping maize were +T+C>+TC>TC before silking, +T+C>TC>+TC from silking to milk stage, and +T >+T+C>+TC after milk stage. Compared with TC, ear grain number and 100-grain weight of intercropping maize under +T+C were increased by 4.14%-65.70% and 1.70%-14.0%, respectively. (3) Compared with TC, the dry matter of intercropping maize at maturity stage increased by 7.39%-21.30% and the yield increased by 19.18%-28.07% under +TC. The dry matter and yield of intercropping maize increased by 10.0%-57.7% and 4.41%-52.00% under +T+C, respectively. The grain yield of intercropping maize was improved by applying phosphorus after increasing temperature and CO2 concentration. These results indicated that elevated temperature and CO2 concentration could promote dry matter accumulation and grain yield improvement by increasing net photosynthetic rate, leaf area index, and leaf area duration of intercropping maize at early growth stage, shortening vegetative growth period, prolonging grain filling time, and increasing ear grain number and grain weight per panicle. Elevated temperature and CO2 concentration had mutual promoting effect on the growth of intercropping maize before silking stage, while increasing CO2 concentration could make up for the inhibiting effect of increasing temperature on the growth of intercropping maize after silking.

Key words: climatic change, intercropping maize, growth, dry matter accumulation, yield
