Can you grow Chuanbei on the family balcony

Fritillary likes cold and cool climatic conditions, and has the characteristics of cold resistance, moisture liking, fear of high humidity, and shade preference. When the air temperature reaches 30 or the ground temperature exceeds 25, the plant will wilt; Areas with low altitudes and high temperatures cannot survive.

Planted under completely shadeless conditions, seedlings are easy to die in patches; Too strong sunlight will promote the evaporation of plant water and strengthen the respiration, which will easily lead to low drying rate of bulbs, slightly yellow fritillary, and easy to become "oil", "yellow" or "soft" after processing.

The planting method of the mother of the Fritillaria.

Before sowing, the furrow is 105-110 cm wide, 10-15 cm high, the trail between the furrows is 40 cm wide, the furrow surface is withdrawn with superphosphate, and the thick cm humus soil is covered after sowing, and then covered with mountain grass to reduce soil moisture evaporation.

In a cool and humid climate, the average annual temperature is required to be 0-6 degrees Celsius, the coldest month is not less than 0 degrees Celsius, the hottest month is not higher than 15 degrees Celsius, the annual precipitation is not less than 700 mm, and the precipitation from October to April of the following year reaches more than 20% of the year; It is better to plant in deep, loose, humus-rich slightly acidic soil. Seed propagation. From July to August, the fruits are harvested from green to yellow, and the seeds are peeled.

Mix humus or sawdust with seeds with 4 times the seed volume, layer into a flat-bottomed ditch or wooden box set up indoors or understory, 40 cm wide and 20-30 cm deep, the layer is 10--20 cm thick, and the cover is 1--2 cm thick mountain grass, etc., to keep it moist. If the thickness of the layer is greater than 10 cm, it will be replanted once every other week.

Maintain the average daily temperature of the lamination at 4-10 degrees Celsius, and the temperature change period is 6--8 weeks or longer. Take the embryonic morphology of mature seeds, sow or withdraw in 3-4 months, and use 3-4 kg per mu.

Seed sowing section.

In the first and second years, it is necessary to cultivate soil after withering seedlings in the growing season, and when the seedlings emerge in the second growing season, apply manure or compost, and when the seedlings emerge in 6-7 weeks and 9-10 weeks, phosphorus and potassium fertilizers are applied outside the roots.

In the autumn rainy and high temperature season, when the weeds germinate and the bulbs are buried in the ground after the fritillary seedlings wither, rake the weed buds several times to reduce the number of weedings. Pay attention to drought prevention, flood prevention, and mud pollution prevention. It can also be propagated with whole bulbs, isolated scales, or cut into scales.

If there is a rust hazard from May to before the dead seedlings, the dead leaves should be removed, and if necessary, every 2-3 weeks, spray with 1000 times of powdered rust. Self-rot disease is watered with 50% carbendazim 500 times solution.

You can let him go and start your life all over again.

If you fall in love in the future, don't give more than the other party. The one who pays more suffers more damage.

Don't dwell on the unchangeable things that have happened, learn to accept and learn to pass.
