How many forsythia seedlings need to be planted in one mu of land? What is the economic benefit of planting?

Spring primrose blossoms each other, adding a lot of color to both sides of the road, and Forsythia suspensa, which is very similar to its shape, blossoms at this time, so how many forsythia seedlings need to be planted in an acre of land? What is the economic benefit of planting?

How many forsythia seedlings need to be planted on one mu of land?

Forsythia is generally flowering in early spring, like light, warm, humid climate, but also very hardy; resistant to drought and barren, but afraid of waterlogging. Generally, it can be planted in spring, summer and autumn, and about 300 seedlings need to be planted in one mu of land, and the specific planting amount should be determined according to seedling specifications and topography. In addition, we should pay attention to the following points when planting:

1. Selection of planting plots of Forsythia suspensa

Sand entrainment land with deep soil layer, loose and fertile soil and good drainage is the best, or it can be cultivated in a piece of mountain or gentle slope against the wind; if it is not large-scale planting, it can be planted sporadically, such as wasteland, roadside, field edge, ground angle, front and back house, courtyard gap and so on.

two。 Temperature conditions of Forsythia suspensa

The optimum growth temperature of Forsythia suspensa was 18-20 ℃, and the growth of Forsythia suspensa was inhibited when the temperature was higher than 35 ℃ or lower than-15 ℃. The suitable temperature of sowing time is 10-15 ℃, the optimum temperature of flowering stage is 18-20 ℃, and the annual frost-free period should be more than 170 days during the growing period.

3. Water and Fertilizer Management of Forsythia suspensa

In the natural distribution area, the annual precipitation is 800mm to 1000mm, and the relative humidity is 60% to 75%. If there is too much precipitation, remember to discharge the stagnant water in time; apply thin fertilizer frequently at the seedling stage of Forsythia suspensa, and apply rotten stable fertilizer, cake fertilizer or soil miscellaneous fertilizer in combination with loose soil and weeding every winter, and increase fertilization once before flowering in spring. In the seedling stage, forsythia should often loosen the soil and weed, and after planting, it should be ploughed and weeded next to the forsythia tree once a year in winter.

4. Shaping and pruning of Forsythia suspensa

After defoliation in winter, the top shoots are cut off when the young trees of Forsythia suspensa are about 1 meter high; in summer, 3-4 strong branches are selected for cultivation as secondary main branches; and every winter, withered branches, wrapped branches, overlapping branches, cross branches, weak branches, overgrown branches and branches of diseases and insect pests are cut off.

Second, what is the economic benefit of planting Forsythia suspensa on one mu of land?

Forsythia suspensa is a kind of plant which has been planted for many years, which has considerable economic benefits, and the economic benefits produced by different topography are different.

1. Benefits of planting Forsythia suspensa in barren hills

Forsythia suspensa planted in barren mountain is about 200plants per mu, and the yield of 3-year-old Forsythia suspensa per plant can reach 0.4kg; in the eighth year, the yield per plant can reach 1kg; in the peak fruit period, the yield per mu can reach 200kg, calculated at the price of 40 yuan per kilogram. The income per mu can reach 8000 yuan, and the benefit after excluding the city is about 5000 yuan.

two。 The benefit of planting Forsythia suspensa in Pingchuan is about 400. the yield per mu can reach 480,600kg, the output value ranges from 9600 to 12000 yuan, and the benefit after excluding the cost ranges from 7600 to 10000.

The above is all about forsythia planting, hope to solve your problem.
