Grapes many times a year result technology
The results of multiple grape harvests in one year are divided into two methods: the use of winter bud secondary results and the use of summer bud secondary shoot secondary results: 1. Using the winter bud a shoot tip twice a year results technique to use the winter buds on the buds of the year to make secondary As a result, due to the better differentiation of winter buds, the secondary results yield and quality can be guaranteed. Therefore, secondary shoots of winter buds are commonly used in production to form secondary results in one year. When using the secondary results of winter buds, the technical key is to Forcing and accelerating the differentiation and formation of flower buds in winter buds of the year; second, the buds of the winter buds should be germinated neatly in order to ensure that the fruits mature fully in the year. The main measures are: (1) The main shoots are picked up from the winter buds of the year. Inflorescence differentiation has begun from flowering to early flowering. Therefore, when winter buds are used for secondary results, the tipping of the main shoot is generally carried out with 4-6 leaves above the inflorescence, and the main purpose of this topping is to promote nutrient concentration of the tree. In winter buds, to promote flower bud differentiation is more fully. (2) After removing the main tip of the auxiliary tip and removing the tip, remove all the auxiliary tips so that the nutrients are completely concentrated and transported to the top 1-2 winter buds to promote early sprouting of the winter buds. If the first bud of winter buds shoots, there is no inflorescence. At the same time, this winter bud apron can be cut off together with the tip of the main shoot to stimulate the inflorescence of winter bud under the shoot. Since the winter bud has a longer development time, the inflorescence in the bud of the winter bud is well differentiated and the knot strength is relatively strong. In order to produce better quality winter a shoots, the secondary shoots are generally erased twice. The first time the middle shoots are first erased and the upper 1-2 shoots are temporarily retained. Two 2-3 leaves of the secondary shoots were left to pick up the hearts, and about 10-15 days after the first secondary shoot was removed, the 1-2 secondary shoots were removed to promote winter buds. The new shoots of winter buds are not only neat and consistent, but also the inflorescences in winter buds are large and robust, and the seed setting rate is also high. By controlling the timing of cutting off the tip of the apical shoot, the germination time of the winter bud can be controlled. Although delaying the germination time of the winter bud can increase the strength of the inflorescence node, the second branch drawing of the winter bud directly affects the growth and maturation of the fruit. Therefore, attention must be paid. The winter buds must not be too late. In North China, the suitable time to cut off the top secondary shoots to force winter buds is from the end of May to the beginning of June. Other regions can decide flexibly according to the specific climate conditions in the area. 2. The secondary result technology of the secondary shoots of summer buds is used to cause the sprouting of the summer buds immediately followed by the formation of germination, and once the summer shoots are germinated, it is easy to pump the secondary summer shoots. This can easily cause nutrient dispersion and the flower buds are not easily formed or formed. Flower buds are not of high quality. Therefore, when using the secondary results of the shoots of summer shoots, we must first ensure the good formation of inflorescences in summer shoots. This is the key to using the secondary shoots of the summer shoots to carry out the secondary results. It is precisely because of this that the secondary results of the summer shoots are used. The time required for topping and erasing secondary shoots is very strict. (1) Tip topping: When secondary shoots are used, the buds must be picked before the sprouts have germinated to form flower buds. Therefore, the picking time must not be too late, due to the 1-3 leaves of the main inflorescence of the Eurasian species. Summer buds in the festival are prone to flower buds. Therefore, the main shoot tipping time for the purpose of promoting secondary results is about 1 week earlier than the general picking time. It is also determined in conjunction with the specific environment of a region and the status of flower bud formation in the species. The key point is to make sure that one or two summer buds below the topping point are not yet sprouted. This must be noted. (2) Erase all the shoots of summer shoots: At the same time when the main shoots are picked up, remove all the shoots that have sprouted on the main shoots so that the nutrition of the tree is concentrated on the top 1-2 unheated summer shoots. In order to promote the formation of flower bud differentiation, generally after the main shoot topping, the top summer buds can be germinated in about 5 days. If the management is strengthened, a good summer bud abutment inflorescence can be formed. (3) For the secondary shoots with inflorescences that have been extracted, the hearts should be picked up at 2-3 leaves above the axillary shoots to promote the normal growth of the inflorescences that have been sown. (4) If the induced summer shoots are not formed with inflorescences, they should be picked up again when they exhibit leaves of 4-5 leaves, and the result of secondary shoots should be promoted. However, attention should be paid to the following when picking hearts: 2 buds that have not yet sprouted.
