In order to offer an information concerning about the nutrients variations in growth stage of corn (Zea maize), more over, to present an advantageous cultivation accompanied with useful land utilization, studies were conducted in 1972 autumn~1974 spring. A Close-spacing and Thinning cultivation method was applied and four of periodical products in every crop were subjected to chemical analyses. The results of each crop were shown in Table 1~4.
It was found that an extremely rapid growth of corn appeared two-month after germination and it was recognized that the maximum nutrients formation of corn was got in this period.
With the Close-spacing and Thinning method, one could obtain about two folds production of protein and above one and a half production of other nutritive constitunents, including calories, when compared with ordinary cultivations. The details were shown in Table 6.
The data of experiments showed valuable of Close-spacing and Thinning method, even though, unfavourable effects of Close-spacing were also observed, therefore, too tight Close-spacing is undesirable from the points of view, such as reduce in yield, needs of much seeds and labours, and so on. The moderate design for the Close-spacing seems to be that starting from 30×15 cm to 60×30 cm in row and space distances via once thinning process.
At last, it should be emphasized that enough moisture contents of soil is the principal factor in corn cultivation, and it becomes more important for a Close-spacing plantation.
