Description
Technical field
The present invention relates to fruit tree fertilizer.It is soluble solid that sweet tea persimmon percentage of fertile fruit, fruit weight and fruit are improved more particularly, to one kind
The special fertilizer and fertilizing method of shape thing.
Background technology
Persimmon (Diospyros kaki L.) originates in China, is the important woody grain seeds in China, is described as " the iron village
Sow ", there is the cultivation history of more than 2000 years.According to FAO's data statistics, China's persimmon cultivated area in 2013
74.01 ten thousand hectares, area and yield are the first in the world, and persimmon turns into China's area the 4th, the main economic woods of yield the 6th
Seeds, 361.88 ten thousand tons of annual production, and sweet tea persimmon yield only accounts for the 2% of persimmon total output.At present the sweet tea persimmon kind 90% in China be from
Japan introduces, such as ' Yang Feng ', and domestic sweet tea persimmon less varieties, its poor quality, item property are bad, and international competitiveness is weak, causes
Sweet tea persimmon industry development is slow.
Positive Feng Tian persimmons (Diospyros kaki cv.Youhou), belong to complete sweet tea persimmon, are opened from China's eighties in last century
Beginning introduces a fine variety Japanese Sweet Persimmon, and the whole nation introducing and planting.Plucked as apple instant.With fruit big, lovely luster, good quality etc.
Feature, it is well received by consumers.It is serious to presently, there are physiological fallen fruit, yield is relatively low, the serious hair for restricting China's sweet tea persimmon industry
Exhibition.
The persimmon kind of China's cultivation, the overwhelming majority is puckery persimmon.《Fruit tree will》963 product for the relevant persimmon recorded
In kind, only the ground such as Luotian County of Hubei Province produce sweet tea persimmon, be to originate in China's uniquely complete sweet tea persimmon (naturally taking away the puckery taste), also known as
" China native nonastringent persimmon ", especially using the sweet tea persimmon in Zan Zishi villages as top grade, taken away the puckery taste naturally when fruit is ripe in the tree, taste is unique, have it is delicious,
Gorgeous, the features such as sweet tea is crisp, tasty and refreshing, it is described as " international treasure ".
In view of the more puckery persimmon of the market price of sweet tea persimmon is high, it is therefore necessary to it is heavy and solvable to improve sweet tea persimmon percentage of fertile fruit, single fruit fruit
Property solid content, so as to improve the quality of sweet tea persimmon yield and sweet tea persimmon, for orchard worker volume increase, extra earning.But sweet tea persimmon fruit setting of the prior art
Rate, single fruit fruit weight and soluble solid are than relatively low.
