Coconut Nuts and seedlings

Published by the Ministry of Agriculture of the People's Republic of China
Implemented on July 1, 1999
NY/T353-1999
Coconut is one of the main woody oil crops in tropical areas. In addition to the fruit being directly consumed, the inside of the fruit can be used as a nut and the peel can be used as fiber. The whole fruit has no medicinal value and is known as a "treasure". Due to the utilization value of the fruit, the production of coconuts has been rapidly developed in tropical areas in recent years, and the demand for coconuts, nuts and seedlings has been increasing. The formulation of this standard will play an important role in regulating the fruit and fungus market and the supply chain of tropical local products in tropical areas: Appendix A and Appendix C of this standard are appendices. This standard is proposed by the Market and Economic Information Department of the Ministry of Agriculture. This standard is under the jurisdiction of the Technical Committee for Standardization of Tropical Crops and Products of the Ministry of Agriculture. The drafting unit of the standard is the Institute of Tropical Agricultural Sciences of the Chinese Academy of Tropical Agricultural Sciences. The drafters of this standard are: Mao Jishun, Qiu Xiaokong, Qiu Weimei, Li Wenbin. The Institute of Tropical Agricultural Sciences of the Chinese Academy of Tropical Agricultural Sciences is responsible for the interpretation of this standard. 1 Scope

This standard stipulates? Definitions, quality indicators, inspection methods and other requirements for packaging, filling, storage and other requirements of different varieties of coconut and coconut seedlings. This bid is for Hainan commercial species, Malaysian yellow fruit dwarf species, and MEwa seedlings. 2 Reference standards The texts contained in the following standards become the provisions of this standard through reference in the other standards. When this standard is issued, the versions shown are valid. All standards will be revised. All parties using this standard should consider using the latest versions of the following standards as much as possible.

Disease and pest control
According to the color of the fruit germination pieces and other characteristics, the seeds are inspected and identified plant by plant. The calculation formula is shown in GB11767.6.1.1.1. The seeds are cross-pollinated hybrid plants and their purity cannot be checked. 6.1.1.2 Yellow Marriage is a self-pollinating plant. However, when there are other varieties of coconuts, it will undergo natural crossbreeding, affecting the purity of the fruit. 353—1999
6.1.1.3 For the hybridization of high quality Chinese magnolia × Chinese magnolia (red, ferrous) varieties, there is a split cross during the hybridization pollination process, which affects the purity of the needle fruit.
6.1.2, germination rate
According to Article 5.6 of GB11?19A9:
6.1.2.1 Germination of Hainan high quality magnolia seedlings, before fruit harvest, starts germination at 40-60 days of germination, and ends at 18 days. The cumulative number of buds is used to calculate the germination rate:
6.1.2.2 Germination rate of Chinese magnolia dwarf seedlings: After fruit harvest, germination starts at 39 days after germination, and ends at 150 days. The germination rate is calculated by the cumulative number of buds.
6.1.2.3 After the fruit is harvested, the hybrid varieties of Mala need to be germinated on the surface for 1 day to start germination, and the germination period is 24(1). The number of buds is calculated.
6.2 Inspection rules
62.1 Fruit quality
15~z after the fruit is harvested, the single quality index of the fruit is tested in parallel: the fruit inspection is carried out at a random sampling rate of (.5%): the fruit produced by the breeding should be accompanied by the seed production inspection certificate (Appendix A):
6.2.2 Inspection
62.2-1 Seedling quality inspection: the seedling quality standard inspection is carried out on the surface of the seedling. 6.2.2.2 Seedling inspection is carried out according to (H11767) 62.2.3 The certificate can be issued if the inspection results meet the following requirements: [The absorption of seeds and seeds should account for 20%~2 %, I level accounts for G0%-5%1 level does not follow 15 purchase
62.2.4 The first shipment should be accompanied by a sample seedling transport verification certificate (see Appendix 6).7 Packing, marking, storage and transportation
7.1 Seedlings should be packed in sacks or longlong bags, and high-pressure mail can also be packed. Seedlings should be packed in this package: small seedlings per 1~2 pieces: large bulk. 7.2 Marking
Seedlings should be packed on the outside to avoid H, and there should be a mark on each package. There is a label, and the batch of seedlings should not be marked. The label model is shown in the attached requirements: 1.3 Storage
Seedlings should be stored in the car, in the shade pool, for more than 1 day, and should be placed in a cool place, spread out, and properly watered, and the time should not be held for 2~3d.
