How to grow covered plates the planting methods and matters needing attention

Covered plate is a common fruit, its shape is a little similar to strawberries, are red. The taste of the covered plate is sour and sweet, and it can be seen every summer when it is ripe. Raspberry has high medicinal value, so it attracts a lot of people to buy it. Therefore, there are many people who grow it now, but before planting, we should have a comprehensive understanding of its planting technology.

How to grow covered plates

Generally, branches, roots and seed propagation can be selected for planting.

The main results are as follows: 1. The seedlings germinated from the rhizome of the mother plant can be used for transplanting. Split-root propagation is when the adventitious buds on the rhizome in early spring have not yet been unearthed, dig the rhizome, cut it according to the length of 10-15 cm, oblique insertion or shallow burial, to keep the soil moist, in order to survive.

2. The seeds are propagated from May to June every year to collect ripe fruit, wash off the fruit, store in wet sand layer and sow in autumn or spring, and transplant after sowing for one year. The most practical method is to dig up new branches and plant them after all the leaves have been lost in December.

3. Cutting propagation will dig out the lateral roots of about 25px, select the roots with buds, cut them into roots about 250px, cut them in the middle of March, dig the deep trenches of 250px, insert the roots obliquely into the border bed, expose 1/4 outside the soil, and bury them flat.

Planting methods and matters needing attention of covered plates

1. Planting methods:

1. Land preparation. Select the slightly acidic gentle slope land with deep soil layer, fertile and loose, and good drainage, and turn the soil deeply. Transplant according to the row spacing of 50 cm × 100 cm or 100 cm × 100 cm.

2. Build a garden. East China raspberries can be planted in spring or autumn, usually in mid-late November or mid-late March. Select the land with shelter from the wind and sun, loose soil, high content of organic matter, moist soil and not suitable for stagnant water to build a garden. before building the garden, it should be ploughed and leveled, and farm manure 2000-4000 kg / mu should be applied.

3. Planting method. According to the strip method, the row spacing is 2 meters and the plant spacing is 0.4-0.8 meters. The size of the planting hole is 30 × 30 × 30 cm. Pay attention to protect the basal buds from damage when planting seedlings. After planting, flat stubble in time, leaving stubble about 20 cm, planting 2-3 plants per hole, to achieve the goal of high yield as soon as possible.

2. points for attention:

Raspberry branches are soft, often drooping to the ground, or easy to lodge in the wind, affecting yield and quality. Therefore, a support is erected in the garden, and the biennial branches are tied to the frame to make the branches receive light evenly and maintain a good permeability in the garden.

Field management of covering plates

1. Intertillage weeding: the raspberry orchard carries out 2 or 3 times of intertillage weeding every year. Loosening soil and weeding should be removed early and small, and chemical herbicides can also be used. At the same time, in order to improve the utilization rate and economic benefit of land and solve the source of land organic fertilizer, we can plant some annual short green manure crops in raspberry orchard, such as beans, potatoes, vegetables and so on.

2. Water management: the root system of raspberry is very shallow, so it is not easy to absorb deep soil moisture, so raspberry must be planted on soil with good water holding capacity. Raspberry should be irrigated in time after planting, especially under the condition of drought and little rain, because the soil layer is easy to dry and the soil water content is very low, the roots of young trees can not absorb water and nutrients in the soil, so the roots of young trees should be irrigated in time after planting. Through irrigation, the roots of young trees are closely combined with the soil, and the roots begin to sprout and grow to make the young trees fixed.

Common diseases and insect pests and their control

1. Stem rot. Prevention and treatment: clean the garden in autumn, cut off the diseased branches and burn them centrally to eliminate the pathogen. It can be sprayed and controlled from May to August. In the early stages of the disease in mid-May and July, the susceptible varieties were sprayed with 500 times of methyl topiramate or 40% of ethyl aluminum 500 times or thiram 500 times, respectively.

2. Powdery mildew. Prevention and treatment: clean the garden before preventing cold in winter, burn the diseased leaves and branches centrally, and eliminate the pathogen. Before sprouting in early spring, after flowering and young fruit stage, spray 1000 times of methyl topiramate wettable powder, or 1000-1500 times of 25% trimethoprim wettable powder, or 1000-1500 times of 50% sulfur suspension.

3. Plutella xylostella. Control method: cut off the damaged branches before adult Eclosion in late August. The raspberry orchard with overwintering soil and cold protection can reduce the occurrence of this insect. Serious raspberry orchards can be sprayed with 2.5% deltamethrin 2000-3000 times during the active period of early instar larvae from late May to early June.

Cover the plate when planting must do a good job of site selection, and then sow seeds at the right time. Field management after planting is also very important. Weeding, fertilizing and water, and the prevention and control of diseases and insect pests need to be well managed every step. Only by doing a good job can we make the plate cover grow better.
