Mulberry planting techniques: timely transplanting and controlling planting density are the key factors of planting.

China is the earliest country in the world to grow mulberry and sericulture, and sericulture is also one of the great contributions of the Chinese nation to human civilization. There are many varieties of mulberry, and the planting area is also extensive, so the environmental requirements for planting are not high, no matter the soil in the mountain area or the plain can be planted. Mulberry orchards are generally built on fertile loam with deep soil layer and low groundwater table, with open topography, good light conditions, prosperous growth, high yield and good quality in air-ventilated orchards. Let's take a look at the mulberry planting technology. Timely transplanting and controlling planting density are the key factors for good planting.

First, how to prepare the land? What kind of base fertilizer should be applied?

In order to prevent waterlogging, facilitate drainage, and ensure soil ventilation, tractors can be used to open ditches and ridges, and then repair them manually. Before planting, the land is generally turned over deeply and leveled, and cross trenches and side trenches with both width and depth of 60cm are opened by tractors to form a ridge with a width of 2.5 m and a ridge height of 30~40cm. The planting ditch was dug on both sides of the ridge, the depth and width of the ditch were 50cm, the bottom of the ditch was covered with a layer of straw about 20cm, covered with 10cm topsoil, and then applied organic fertilizer and N, P, K compound fertilizer, and then backfilled. The types of fertilization were straw 1000~2000kg/667m2, organic fertilizer 1500~3000kg/667m2 and compound fertilizer 50~100kg/667m2.

Second, when do you usually transplant?

Usually from February to March in spring, seedlings are transplanted before sprouting. In the south, because of the mild temperature in winter, it can also be transplanted after falling leaves at the end of autumn.

Third, what kind of planting density is appropriate?

The planting density is determined according to the climatic conditions, site conditions, soil fertility and variety characteristics of the planting area. In general, the row spacing of Arbor rootstock planted on flat ground was 2.5m wide row, 1.5m narrow row, 1.0m plant spacing and 333 plants / 667m 2, while that of dwarfing rootstock planted on mountain, hilly and tidal flat was 2.0m wide row, 1.0m narrow row, 0.8m plant spacing and 555 plants / 667m2. In order to enter the high yield period of the orchard as soon as possible, the plant distance can be reduced by half when transplanting, and the plant thinning can be carried out after 2-3 years.

Fourth, what is the planting method?

When planting, put the seedling in the planting hole, pay attention to straighten out the root system so that it extends around, in the process of filling, the seedling should be slightly raised so that the root is in close contact with the soil, and then firm. The planting depth is the same or slightly deep as the original growth depth of the seedling in the nursery. Finally, fill the remaining soil, water and seal the hole, and cultivate the height of the whole ridge around the stem of the seedling. If the weather is dry within 15 days after planting, it should be watered according to soil moisture.

When will the harvest be ready?

The harvest time is usually from April to June all over the country, and the harvest time is determined according to fruit maturity, use and market demand. Those sold locally should be harvested when the fruit is fully ripe; those with long-distance transportation or storage and fresh-keeping should be harvested at well-done 's time; varieties with different maturity should be harvested by stages. When the mulberry has just changed from red to black (the pedicel of the white variety has changed from green to yellow and white), and the crystal is bright, it shows that the mulberry is ripe and should be harvested in the early morning or evening, but not in high temperature, rainy days and dew at noon.
