Development and Utilization of Hainan Coconut Germplasm Resources
Hainan coconut is mainly divided into two types of fresh food and processing. Fresh fruit is generally used for tender fruit, and it is mainly supplied to the tourist markets in Hainan and the fruit market in major cities in the country. As a fresh fruit drink, it has the advantages of beautiful appearance of coconut fruit, better flavor, moderate fruit type, and convenient portability. Dwarf coconuts have the advantages of fresh and tender fruits. They belong to early-maturing and early-maturing varieties. The fruit size is moderate, and the high yield can reach 200 per plant. The coconut meat is delicate and sweet, the coconut water is delicious and sweet, and the dwarf and tender fruit is not only price 2 to 3 times higher than high-yield fruit, and the yield is also 2 to 3 times higher than high-yielding fruit. Therefore, all kinds of fresh-food coconut dwarf species will use its economic benefits will be high 4 to 9 times.
At present, although the direct consumption of fresh fruit can not be accurately counted, it can be roughly estimated based on the number of Laiqiong tourism. It is assumed that according to Joan Qiong’s 20.6 million visits in 2008, the per capita consumption will be 2. For tourism-driven consumption alone, at least 4 1.2 million, plus consumption in the province and shipped to the mainland market, consumption will not be less than 70 million. According to calculation of 1 800 coconuts produced per 667 m2 of dwarf species, the planting area of ​​fresh-food dwarfs should be at least 2,594 hm2, accounting for about 6% of the total coconut area in the province.
Coconuts used in deep processing in Hainan coconut processing company mainly produce varieties with prolific coconut. Wenyou 78F1 combines the advantages of dwarf coconut and Hainan high species, with fast growth, early maturing (3 to 4 years of flowering results), high yield (The yield per plant is about 120, which is 3 to 4 times higher than that of high-grade coconuts), multi-resistance (resistance to wind, cold resistance), good quality of dried coconut, etc. Although it is the most suitable host plant point of coconut leaf beetle, it is damaged. The possibility is relatively large, but the comprehensive factor is still a hybrid with obvious advantages compared to other coconut varieties. If it can be used to gradually replace the local high species of Hainan, not only can increase the income of coconut farmers, but also can ease the problem of processing raw materials.
It can thus be seen that the establishment of a suitable coconut germplasm resource pool is conducive to greatly improving the economic benefits of coconuts. Coconut is a local feature of Hainan and it can create certain economic value for Hainan every year. Therefore, if it is able to establish a library of crop germplasm resources, it will greatly benefit the survival of the fittest.
