The culture method comprises the following steps: A1, enabling the Qinguan apple tree to be subjected to branch grafting or bud grafting on the Qiaohuaxinhongxing apple tree; A2, enabling the cultured Qiaohuaxinhongxing apple tree obtained in the step A1 to be subjected to branch grafting or bud grafting on the Qiaohuachangfu No.2 tree; A3, enabling the cultured Qiaohuachangfu No.2 tree obtained in the step A2 to be subjected to branch grafting or bud grafting on the M26 dwarfing interstock; and A4, enabling the first cultured M26 dwarfing interstock obtained in the step A3 to be subjected to branch grafting or bud grafting on the red fuji spur apple tree, so as to obtain the apple tree of the new species. The invention also relates to a breeding method of the apple tree of the new species. The breeding method comprises the following steps: grafting the M26 dwarfing interstock on selected tree seedlings, and grafting the branches or buds of the apple tree of the new species on the M26 dwarfing interstock. The fruit tree obtained by the culture and breeding methods for the apple tree of the new species has the advantages that the quality is good, the fruiting period and the mature period are advanced, and the fruits are larger, uniform in color, palatable in sweetness and crispness, large in yield and high in economic value.

The invention discloses a method for fruit cracking control for Lingwu long jujube, which includes: selecting a yard, cultivating Lingwu long jujube, regulating greenhouse covering time, regulating tree crowns and fruits and flowers, regulating temperature and humidity, regulating nutrition, controlling pests and diseases and the like. The base of a trunk of a Lingwu long jujube tree in a full bearing period is girdled at a position 10-15cm away from the soil, girdling width is no larger than one tenth of the diameter of the trunk, and gibberellin 15-20mg / L is sprayed once to twice during the full-blossom period at an interval of 7-10 days. Nutrients are sprayed to enhance thickness and hardness of fruit peel before flowering of the Lingwu long jujube tree and in the medium and late stage of fruit development. By means of the method, application of advancing maturity to controlling fruit cracking in protected cultivation of Lingwu long jujube is successfully and technically broken through in Jinghai county of Tianjin, the technical problem of fruit cracking which bothers jujube growers for long is solved effectively, yield and quality of fresh jujube are improved, insecticide spraying frequency is reduced, insecticide residue is decreased, the safe and nutritious health food is provided for consumers, a new way of increasing income for jujube farmers is exploited, and remarkable economic benefit and social benefit are achieved.

This invention relates to an apple tree nutrient injection and the method for making the same, belonging to the fertilizer technology field. The acidity of the said apple tree nutrient injection is usually pH 2-3, and the procedures comprise: treat the black liquor by biochemistry process to produce the powder, use the filter liquor of lignin and iron chelate as the mother liquid, dissolve the saccharose, urea, ZnSO4 and borax in this mother liquid, mix this liquid with the above powder to produce the product. This invention processes the straw pulp black liquor and lignin, with a lot of consumption of straw pulp black liquor and lignin, to transform them to be usable fertilizer, which greatly decrease the pollution, resulting economical and environmental benefits. Besides, the produced fertilizer is used by direct injection, which avoids the disadvantages of low fertilizer utilization coefficient and environmental pollution brought by the traditional fertilizer application method, and overcomes the problems of low effective time and single nutrient of the traditional fertilizer.

The invention relates to a processing and preservation method for eating fresh walnut, which includes the fresh walnuts is selected after being picked firstly; attacked and rotten walnuts are picked out; a freeze thawing method is utilized to shuck off the green peels of the walnuts and then the freeze thawing method is utilized to shuck off the seed capsules of the walnuts; the walnut meat, the seed capsules of which are shucked off, is dipped in a VC solution with the chroma of 0.1 to 0.8 percent for 1 to 2 hours to carry through color protection; simultaneously, the water content is controlled and then vacuum or inert gas packing is carried through by classification; then the product is frozen to keep fresh until being sold and used. During the whole processing and preservation process, no antiseptic and antistaling agent are used, thus according with the requirement of nuisance-free products and belonging to green healthy food. The prepared walnut meet keeps the fragrance of the walnuts with the flavor of crisp and sweet; the nutrition matters are not washed away and the flavor as well as the quality of the walnut meet is better; and the walnut meet is convenient to eat. The invention has the advantages of keeping the nutrition component of the walnut meet to the utmost extent, improving the using value and eating quality, belonging to nuisance-free green food and being convenient to eat, etc.
