1.Japan's modified mother-tree orchards established at various research stations are very impressive indeed. Selections and clones planted at reduced spacing have rendered an efficient management possible. As a result of reduced spacing the amount of propagation materials produced per unit area of land have been much more than those from the conventional mother-tree orchards. The intensive and modified mother-tree orchards developed in Japan are as a matter of fact the backbone of modern citrus industry.
2.Intensive windbreaks and perfect mulching observed at various citrusproducing centers are regarded as very effective means for promoting both tree development and dependable high yield. In a field trip to the centers, annual pruning of windbreaks to ensure better fruit production was observed. In one prefecture 80% of the orange orchards resort to mulching to effectively control soil erosion. The nationwide average indicated that mulching is practised by 38% of the orange orchards.
3.Fruit thinning, pot-culture and rootstock studies are the common practices of farmers'orchards and experimental stations. We have found that fruit thinning is effective in regulating annual production; the pot culture, an ideal way to study citriculture on limited land, is desirable for conducting different phases of studies with special reference to the controlled soil conditions under which the behavior of root growth as well as the topresponse could be efficiently studied. The rootstock studies conducted at experimental stations for a number of years provided us with valuable information on the yield, quality and maturity of new varieties which have contributed greatly to the development of the citrus industry in Japan.
