Efficient artificial seed extraction method of litchi cross bred fruits

Abstract

The invention provides an efficient artificial seed extraction method of litchi cross bred fruits. The method comprises the following steps: collecting mature litchi fruits; fixing the fruits, glidingly cutting from the middle of a litchi fruit to the middle of the other side of the litchi fruit through a cutter, so as to form a cut around half of the fruit; thirdly, separating a peel with flesh at the cut at the bottom of the fruit, and taking out a seed. According to the method, a comparative test is performed through cutters, such as a paper cutter or a fruit knife, the effect that the fruit is cut and the seed is taken out through a surgical knife handle with a surgical knife blade is achieved, the effect is best, and the efficiency is the highest. Fruit cutting and fruit peeling are performed separated, and flow process is performed. The seed extraction efficiency of the litchi cross bred fruits is improved. The method has the advantages that the peel and the fresh are separated completely so as to be processed and utilized after seeds of the litchi cross bred fruits are extracted, and economic benefit is obtained while the seed extraction efficiency of the cross bred fruits is improved.

Description

technical field [0001] The invention belongs to the field of fruit tree breeding, and in particular relates to a method for artificially picking seeds from litchi hybrid fruits with high efficiency. Background technique [0002] Litchi is a native and specialty fruit in southern my country. It is one of the most important economic fruit trees in Guangdong, Guangxi, Fujian, Hainan and other provinces. At present, there are problems such as irrational variety structure and high concentration of maturity in litchi industry. Variety innovation is the key to solve the problem. An important measure of both of these dilemmas. Hybrid breeding is the most important way to realize litchi variety innovation. Litchi hybrid breeding is time-consuming and laborious, and it is very difficult to obtain fruits, especially artificial hybrids, whose seeds are extremely precious. When obtaining hybrid seeds, it is difficult to ensure that the hybrid seeds are intact, and the growth point at th...

Problems solved by technology

[0003] Litchi seeds are recalcitrant seeds. When the seeds leave the mother plant, they do not need to go through the mature dehydration period. Their water content is relatively high and they are highly sensitive to dehydration. Once dehydrated (even if the water content is still high), the germination process will be affected, resulting in rapid loss of vitality

Litchi seeds are not resistant to storage and have a short lifespan. After harvesting litchi fruits, the seeds should be taken out in time to ensure the vitality of the seeds

The seeds at the pedicle of litchi fruit are closely connected to the pulp, and the pulp needs to be peeled off to obtain the seeds, which is difficult to operate

[0004] Currently there are several lychee peeling machines on the market, which can peel off the skin, pulp and seeds. This method makes the seeds vulnerable to mechanical damage and cannot be used as a method for hybrid fruit

Manual seed picking is a common method to obtain hybrid seeds at present. The seeds at the pedicle of lychees are closely connected with the pulp, and the pulp is thick. It is time-consuming and labor-intensive to peel it off directly by hand.

During the litchi harvesting period, a large number of hybrid fruits are harvested every day, which requires a lot of manpower, and it is difficult to ensure that the seeds of hybrid fruits are removed in time
