Have you ever heard of double-season red raspberries? How much do you know about double-season red raspberries? Do you know how to grow double-season red raspberries? How much do you know about planting techniques and management methods of double-season red raspberries? The editor has collected a lot of relevant information for you. I hope it can be helpful to you. If you are interested in the planting method of seasonal red raspberry, you can take a look at it with me, which can increase your common sense of life.

How to grow double-season red raspberries

The main results are as follows: 1. garden cultivation: it is suggested that sandy soil should be selected to build a garden, and the soil PH value should be 6.5-7.0. the planting ditch should be planted in the spring and autumn season, with a depth and width of more than 0.5m, a row spacing of 2.0m × 0.3m and 1110 seedlings per mu. It is best to apply sufficient base fertilizer at one time. Soak the seedling root in water for 4 hours before planting, and the cultivation method is very simple: dig the pit according to the length, width and depth of 10mur15cm, unfold the seedling root into the pit, and bury the soil; the key point is: the seedling root and the soil around the seedling should not exceed the original watermark of the seedling in the nursery; where there are conditions, do not rain, water or cover after planting to ensure the survival rate.

2. management of growing period: in the planting year, only general weeding, watering and loosening soil management can blossom and bear fruit in the autumn of that year, and the fruit of the 2-year-old branch will be harvested in July of the following year, and the fruit of the mother branch will be cut off from the base after harvest; the fruit of one-year-old branches germinated in the same year was harvested from August to September.

3. Overwintering against cold: in the cold areas of the north, it is necessary to bury branch soil for two years to prevent cold, to prevent flower buds from freezing and branches from draining. When burying the soil before freezing, the selected branches are pressed and tied in one direction, and then the buried soil (about 15 cm thick) is tightly covered, frozen in winter, and then cooled and removed.

Planting techniques and management methods of double-season red raspberry

First, planting techniques of double-season red raspberry

1. The choice of garden land.

In fact, raspberry is a perennial rhizome perennial herb, it likes light, temperature, need to choose ventilation, light, fertile soil, convenient irrigation plot to build a garden. Sporadic plots and planting in front and behind houses can also be used to not only produce fresh fruit, but also beautify the environment. At present, most of the raspberry fruits are exported to Europe and the United States, and the environmental requirements are very strict. therefore, with the development of industrialization, we should choose the land far away from the source of pollution.

2. Soil preparation

The soil should be cultivated thoroughly before planting to eliminate weeds, and if the terrain is low, drains should be dug. The suitable distance between rows and plants of double-season varieties is 1.5 × 0.4 meters. 1110 seedlings per mu, single plant in a single hole, about 3 kg of mature farm manure can be applied in each hole and mixed with the surface soil, which can play the role of drought resistance, anti-mite and high yield.

3. Planting period and method

Raspberry planting period is mainly spring sowing and autumn sowing, as well as summer planting, winter sowing (south) and so on. It can be planted in the early stage of seedling germination after soil thawing in spring, and can be planted in the north when the soil thaw 15cm is deep, and early planting is suitable for spring planting. It is better to plant in autumn after the seedling is textured to before the soil freezes. The survival rate of autumn planting is high, the spring germination is early and the growth is fast. It is best to master one month before the soil freezes. After autumn planting in the north, the remaining branches on the ground should be cut off if possible, and the cut should be covered with soil about 2 cm or wax sealed before freezing to maintain moisture. Remove the soil in time after thawing in spring so as not to cover the buds. Summer planting is generally carried out in the first and middle of June, when the root tiller seedlings grow to 30-40 cm, the tender seedlings with soil and complete roots are planted into the planting hole, the seedlings should be irrigated in time, water again after 3-5 days, and the seedlings begin to grow in 7-10 days. Summer planting is mainly suitable for seedling replenishment in the field or planting in the nearby area. Winter planting is a suitable planting method for growers in the south. In early or late winter, when the soil is not frozen, the false seedlings from autumn will be planted in time. The advantage of this planting method is that the seedlings can have a dormant period after planting, and as the temperature increases, they can gradually adapt to the local climate and improve the survival rate.

2. Management methods of double-season red raspberry

In fact, raspberries, like other crops, need routine management such as weeding, loosening the soil and watering during drought. The pruning of double-season raspberry is relatively simple. after the seedlings germinate in spring, the thin and weak branches and damaged branches can be cut off at any time, and the overdense roots and tillering branches can be cut off or transplanted at any time. After the autumn fruit, all the branches will be cut off, so there is no need to bury the ground to protect against the cold. There are more than 3000-4000 branches in the high-yield period, in order to ensure convenient management, ventilation, light transmission, plant gap, row distance and easy harvest.

How to fertilize double-cropping red raspberry correctly

1. In fact, raspberry fruit trees are more resistant to barren and adaptable, and the raspberry petiole is composed of epidermis, basic tissue and vascular bundles. Raspberries carry out deep ploughing and renovation of the soil before planting to remove surrounding weeds. Raspberry in the planting process should be carefully managed, should keep the raspberry planting environment with enough sunlight, can better ensure that the raspberry can survive the winter safely. Gardeners should timely water to ensure sufficient water between raspberries, trim branches regularly to ensure the growth and fruiting rate of healthy branches, and cut off some rotten branches and leaves to ensure the healthy growth of the whole tree. Because raspberry is a sunny plant, raspberry has strong adaptability, it can survive in all kinds of soil, especially some acidic sandy soil is more suitable for raspberry growth, so try to choose sandy soil area. After planting raspberries, fertilizers should be added to promote the survival of raspberry seedlings.

2. We should use raspberry fruit varieties with good disease resistance to plant raspberry fruit trees. After raspberry planting, in order to improve the fruit setting rate of raspberry, timely application of 50% vegetable garden soil, 30% coal ash or sawdust, 10% rotten barnyard manure and 10% loess to prepare basin soil is more conducive to the results of raspberry. The best temperature for raspberry growth is 18 ℃-32 ℃, and the growth is slow below 5 ℃ or above 35 ℃. Raspberry fruit trees prefer fertilizer and should apply nitrogen-based quick-acting chemical fertilizer once or twice when new buds germinate in spring. When raspberry enters the initial flowering stage, it is necessary to apply compound fertilizer based on phosphorus and potassium for two or three times. During the fruit setting period, the plant ash extract should be applied every 10 days or so to increase the fruit setting rate and promote the rapid expansion of the fruit. Raspberries like to flood during the peak growth period, especially in the hot season. Water should be watered every morning and evening to keep the basin soil moist. Raspberries should be watered properly during flowering in order to improve the fruit setting rate. For the healthy growth of young raspberry trees, the compound fertilizer of nitrogen, phosphorus and potassium is the best for the growth of young raspberry trees. Garden staff to strengthen the management of raspberries, more conducive to improve the yield and quality of raspberries.

After the introduction of the editor, how much do you know about double-season red raspberries?
