Short-spike cuttage technique for growing tea in autumn
At present, the development of famous and high-quality tea is the inevitable way for Yuyao tea to take benefit agriculture, and the effective way to develop early-growing varieties is short-spike cuttage, which not only maintains the excellent characteristics of the mother tree, but also shortens the breeding years, thus speeding up the speed of reproduction. But short spike cuttings

Seedling raising technique of short-spike cuttage of tea plant in nutrient bag
The technology of short spike cuttage of tea plant in nutrient bag is a process of directly cutting short spike in nutrition bag and cultivating plants. This method of asexual reproduction can effectively maintain the characteristics of the female parent tea tree, and the characters of the offspring are the same, which is conducive to the cultivation of strong seedlings, transplanting without harming the root system, and effectively improving the survival rate. However, the technical requirements of raising seedlings are high, and the working procedure is relatively complex, which can easily lead to failure if they are not mastered well. Seedlings should pay attention to the following technical points: first, building a shade shed has the function of sun protection, wind protection and frost prevention. It is an important link in the success or failure of raising seedlings in nutrition bags. Shade

Short-spike Cuttage Seedling technique of White Tea
White tea seedlings are generally raised by asexual short-spike cuttings. Experiments show that when white tea is raised with tea seeds, its offspring show character variation, that is, there is no periodic whitening in spring, and short-spike cuttings can maintain the characteristics of female parents. the progeny has the same characters, high reproduction coefficient and high survival rate. Considering the economic benefits of white tea, at present, there is no special mother garden, but both the mother garden and the picking garden. The cutting time is generally from September to October in autumn, during this period, the cuttings grow roots quickly, the seedling rate is high, and the management is short at the same time, which is favorable.

Techniques of short spike cuttings of tea trees in centerless soil
Tea tree centerless soil short spike cutting not only saves the cost than the traditional paved soil short spike cutting, but also the cutting survival rate can reach 85%, which is worth popularizing. First, Miao auxiliary land preparation (1) select the land. The nursery should be close to the water source, the soil is loose, the terrain is flat, and it is convenient for drainage and irrigation. (2) Planning. To adjust measures to local conditions, divide the district according to the natural drop of the land, and dig irrigation ditches around each district, 60 centimeters wide and 40 centimeters deep. The length of the border is generally 10 to 15 meters, and the width of the border is 1 meter. The operating ditch between the border and the border is 40 cm wide, with the border facing east.

Seedling raising technique of short-spike cutting of Lycium barbarum
Lycium barbarum seedlings raised by short-spike cutting is better than seed propagation, which can not only maintain species character and reduce variation, but also have the advantages of large propagation coefficient, simple operation, high survival rate, quick coming out of nursery and so on. First, the nursery bed preparation for raising seedlings should choose sandy loam with leeward direction and convenient drainage and irrigation. The nursery bed is 1 meter wide and the length depends on the terrain and needs. The nursery bed is covered with 10 cm thick gravel and coarse sand, and the upper bed is covered with a mixture of sifted loess, burnt soil and fine sand, with a proportion of 70%, 20%, 10% and 10 cm thick, respectively.

The short-spike cuttings of single-clump tea have obvious advantages in raising seedlings.
Dancong tea is of stable quality and easy to be made into high-grade tea. The finished tea is mellow and refreshing, with honey flavor, and is one of the best oolong teas. The tea has the advantages of wide adaptability, strong stress resistance, early germination and fast growth. Generally, it can harvest 6 mures and 7 rounds a year, with high yield and good economic benefits. The short spike seedling of single clump tea can maintain the excellent characters and characteristics of single clump tea, which is conducive to the establishment and cultivation of new tea gardens with purer characters, and because of the wide source of materials and short seedling raising time, it can propagate a large number of seedlings rapidly, which is a "more, fast, good and economical" solution.

Seedling raising technique of short-spike cuttage of tea plant
First, the selection of mother trees and the cultivation of cuttings: the vigorous growth, the same characters of improved varieties, and the disease-free garden were selected as the mother garden, and then the mother trees were selected in the mother garden, and the selected mother trees did not pick tea, but left shoots to cultivate cuttings, generally leaving spring shoots as summer cuttings, summer and autumn shoots as autumn and winter cuttings, and topping about 13 days before cutting. Second, nursery land selection and management: select areas close to the new planting garden, convenient transportation, loose and fertile soil slightly acidic red-yellow loam, convenient drainage and irrigation. Ploughing and tanning, raking and smashing, removing grass roots, tree roots, sundries, etc. According to the width of the border 1 meter

Management points of the latest early flowering mango tree
Because of the long drought in winter, or the high temperature, the mango tree is very easy to sprout ahead of the Beginning of Spring, leading to early flowering, but it is extremely vulnerable to the threat of overcast and rainy days before and after the Qingming Festival, seriously affecting pollination and fertilization, reducing fruit setting rate, resulting in reduced production.
