一九八○年省农科院果树所引进了泰国和菲律宾的番石榴品种进行试种.经过三年的培育取得良好效果.一九八二年开始结果,一九八三年实生树结果累累.泰国番石榴丰产株结果高达 128粒,最大单果重645克,平均单果重265克,菲律宾番石榴丰产株结果达147粒,最大单果重675克,平均单果重305克,这二种番石榴品种都具有速生、矮化、早结果、高产、果实大、品质清脆、适宜鲜食和加工利用的优点,比我省本地种,果实小,种子多,产量不高等更显得优越.为了充分发挥和利用我省亚热带气候,和发展番石榴的有利条件,建议我省可进一步试种,示范推广.同时因泰国番石榴存在风味较淡的缺点,可考虑用本地种加以改良.生物学特性 番石榴属桃金娘科,泰国和菲律宾番石榴是常绿的灌木丛,树冠矮化开张性,株高
In 1980, the provincial Academy of Agricultural Sciences introduced guava varieties from Thailand and the Philippines for trial planting and achieved good results after three years of cultivation. The results began in 1982 and the results of the 1983 real tree were numerous The highest yield of Thai guava fruit was 128 grains with the largest single fruit weight of 645 grams and the average fruit weight of 265 grams. The results showed that the highest yield of Philippine guava fruit was 147 grains, the largest fruit weight was 675 grams and the average fruit weight was 305 grams. Varieties have the advantages of fast growing, dwarfing, early results, high yield, large fruit, crisp quality, suitable for fresh food and processing and utilization, more superior than the local species in our province, the fruit is small, the seed is more, the yield is not high, etc. In order to give full play to And the use of the subtropical climate in our province, and the favorable conditions for the development of guava, we suggest that the province can further test, demonstration and promotion. At the same time due to the short flavor of the guava in Thailand, the local species can be considered to be improved. The pomegranate genus Myrtaceae, the Thai and Philippine guavas are evergreen shrubs with canopy dwarfing and plant height
