Raspberry High-yielding Cultivation Techniques First, garden choice: Raspberry gardens can have different options depending on the purpose of planting: First, according to the needs of domestic and foreign markets, choose to focus more contiguous land, usually in 100 acres or acres or even acres The above establishes commodity bases; secondly, it promotes the development of a garden raspberry garden with a convenient management of the land behind the houses in front of the house and the sprawling space on the “four sides†(house, road, water, and village). In addition to fresh food, midsummer can be used to process home-grown juices with excellent flavors and fragrances. This is not only suitable for farmers, but also suitable for urban residents, institutions, schools, and military units. It integrates the production methods of beautifying life, greening the environment, and increasing production revenue.
Second, the formation of land: raspberry on the soil is not strict, in addition to heavy alkali and stagnant water need to be modified, the general land can grow normally, but growing better in fertile soil. After first deep-casting the land (adjustable from north to south), the two cockroaches will be merged with scorpions, and the seedlings will be planted after smashing and squeezing. If conditions permit, they can be separated from the original sulcus or newly-turned sulcus. Some farmhouse manure is applied, and the number of farmhouse manures is not limited, and the two crickets are combined into one crop.
Third, the cultivation techniques: Raspberry can be planted in the spring and fall seasons, regardless of north and south, when the ground temperature is around 10 °C, is the best season for planting raspberry, planting roots soaked in water for more than 4 hours before cultivation. The cultivation method is very simple: at the center of the ramen noodle, the row spacing is 1.1 meters and the spacing is 30 centimeters (upright raspberry, can be properly planted: 2000 trees per acre), then dig pits with a width, depth and depth of about 15 centimeters. Expand into the pit, fill the soil and practical; the main point is: deep planting shallow burial; the standard is: the seedlings around the roots and seedlings should not exceed the original soil and India when the seedlings in the nursery, where conditions, not rain after planting Watering or covering the membrane ensures the survival rate.
IV. Post-planting management: The branches of raspberry seedlings are mainly underground rhizomes. The aboveground parts are not as important as other fruit trees. Therefore, when raspberry seedlings are planted, only about 20 centimeters of the upper part (main trunk) is cut off. Survival rate can be increased; within one month after raspberry is planted, the growth center of the plant is underground before the virgin twig breaks out of the ground. Therefore, the survival rate after planting should be checked after two months; raspberry grows. During the period, special arid areas were tarred after watering, and weeding was done using "graceless" or "green" or direct "shelter" to save labor and labor.
Five, branches cited: In addition to the autumn fruit red raspberry plants are more stout erect, set dry 30-70 cm, without scaffolding can flowering results, other species of raspberry, plant opening or pods, must be scaffolded to normal results . Practice has proved that setting up scaffolds for raspberries is also an effective measure for transforming plane results into established physical results (extremely productive): in addition to uniform distribution of shoots and improved ventilation and light transmission conditions, it is important that scaffolds allow plants to withstand higher yields. Fresh fruits are also protected from land contamination. It also facilitates the management of soil fertilizer, water harvesting, and harvesting at Raspberry Garden. A relatively simple rack type: In the row of raspberry every 10 meters buried a column (hardwood column, cement column or metal column can be), on the ground 1-1.5 meters to pull a (8-14) wire, every year In spring, the resulting mother branch of the plant cluster is evenly attached and fixed on the iron wire.
Sixth, pruning and harvesting: the results of raspberry root rhizomes, one can initiate a number of basal and root litchi, when the seedling height is about 30 cm, it is necessary to locate and maintain the basal branches that are robust and close to the plexus. Or root lychees 2-3, ready for the next year results, the remaining plants combined with cultivator weeding all cut off; After the fruit is harvested, from the base to cut all the branches have been fruiting branches, is conducive to the next year the results of seedling growth and development. The life cycle of high-yield and stable production in single bushes is as high as 20 years. The actual maturation period of raspberry fruit is inconsistent, which is conducive to batch harvesting and sales. Since the fruit matures, it is harvested once every 1-2 days when there is no rain or dew, harvested in the morning, with the strongest aroma, and different harvesting methods are used according to different purposes:
1, fresh food sales: fresh fruit can be brought to bear with or without receptacles when the nine mature, after the wholesale or retail; if loaded into a fine plastic box, half a catty per box, and even sell the box with a higher value;
2, frozen processing: in the full ripe fruit, darker berry color, red berry near purple, polymer fruit can easily pick when separated from the receptacle, the collected berries can be packed in plastic bags (5 Jin), with bags They are sold together in a freezer and frozen for sale; or the collected berries are placed in a plastic box (30-40 kg) and sent directly to the processing plant for sale in a freezer.
VII. Winter protection against cold: Only the autumn red raspberry is dried for more than 30 cm, and the results can be achieved without the use of buried soil to prevent cold. However, when the raspberries of other varieties are dried lower, they lose their ability to produce results. Although the raspberry is in dormant period, the mature basal shoots on the ground can tolerate temperatures below -30 degrees and the snow can tolerate 40-45 degrees, but in the cold regions where there is little winter and heavy snow, the growth of basal shoots is delayed. The growth in the upper and middle parts is not substantial, and because of the poor water retention ability of the branches themselves, especially on sunny slope land, the phenomenon of “drafts†is prone to occur, affecting the fruit production volume; in order to effectively prevent basal shoots from “drawingâ€, the current production is mainly The overwintering ability of the tree body is enhanced by effective measures such as overwhelming the basal branches and digging the earth to prevent cold and potting frozen water. It is not advisable to cover the cold in a period of time that is too early or too late, generally at night when the temperature is low, the daytime temperature is stable above 5 degrees Celsius, and the soil freezing layer can be completely thawed.
Operation method: It is appropriate to cut the length of the raspberry berry to 1.8-1.3 meters, strong branch length, weak branch short (deep snow and warm areas do not need to be buried to prevent cold, cutting work can be done in the early spring of the second year, before the mother shoot germination get on). Before the branches are overwhelmed, pile up some pillow soil at the base of the base to avoid breakage. Then push the strains straight in one direction and cover them with a plastic film to prevent water loss. Then move away from the roots. Take the soil between the branches, bury the shoots completely and make a photo with a thickness of 10-20 cm. In the spring, after the sap begins to flow, remove the cold-proof soil and put it on the shelf in time before the bud eye expands. Then, smooth out the soil pit or apply it in the pit. Farmyard fertilizers work better.
