1. THE COMPARISON OF CULTIVATING MATERIALS
The purpose of this experiment is to choose some materials rich in cellulose for Chinese mushroom (Volvariella vovacea (Bull. ex Fr.) Sing.) compost in order to compensate for the shortage of straw. The chosen materials are wasted cotton, sugarcane rubbish and 10% wheat bran mixture, straw alone is used as check. The experiment result shows that with wasted cotton the productivity is the highest and the average production is about22.59 kg/pin; with sugarcane rubbish the productivity is the lowest, average production 6.2 kg/pin. Among the other groups the highest productivity can reach beyond 23 kg/pin, but very unstady, and with sugarcane rubbish and 10% wheat bran mixture the highest produc-tivity can be over 31 kg/pin. For the development of Chinese mushroom industry, the arrangement and composting technique of the various materials mentioned above and the management of cultivation, further experiment is needed.
II. INVESTIGATION ON SUGARCANE RUBBISH FOR CHINESE MUSHROOM CULTIVATION AND ITS GROWTH FACTORS
In this experiment sugarcane rubbish is used for the Cultivation of Chinese mushroom (Volvariella volvacea). Investigation were made on the changes of bed temperature, carbon dioxide, PH value and water containing during the growth period. Experiments were also proceeded on sugarcane rubbish, the addition of 5, 10, 20, 40% of wheat bran respectively and kepping wasted cotton as the check. The result shows that the productivity of sugarcane rubbixh is too low and the average production is 4.21kg/pin/50 kg sugarcane rubbish. The productivity is increased in proportion to the addition of wheat bran but the adding amount of 20% is more economic. In this treatment the average production can reach 23.23 Kg/pin, almost 22% beyond the average production of 18.97 Kg/pin in the check treatment of wasted cotton. During the cropping period, it was found that at each treatment almost 80% was picked within 3 to 10 days. After that there were only limited amount for picking. These facts are worth for consideration to the economic way of cultivation especially, the improvement of productivity, the usage of mushroom house and the saving of man-power.
As to the change of bed temperature during growing period, it was found that from planting until cropping for two weeks, the bed temperature can be maintained at 30˚ to 35˚ C, the optimum range for the growth of Chinese mushroom. Then, the bed temperature decreased gradually and the productivity diminished also. The changes of carbon dioxide in the mushroom bed had the same tendency as temperature did, which was higher in the earlier period but lower in the later period. Obviously, the changes are in periodical pattern.
The peak of these periodical changes are always reached earlier than the peak of productivity (Fig. 1-6). This phenomenon is related to the increase of respiration during the formation and the rapid growth of fruit-body. The change of PH value during the growth period is between 6 and 8. The water contaning is around 80% with few changes. As the physiology of fruit-body formation is concerned, the suitability of the humidity be still in question. In short words, the knowledge of Chinese mushroom cultivation are very limited and further researches are needed.
