How to cultivate Flower and cultivate the Disease Control of Flower Blue

Flowers and trees blue can grow in a more stringent environment, the requirements of the soil is not very strict, is a very good breeding plants, let's take a look at how to cultivate flowers, flowers and trees blue disease control.

I. cultivation techniques of Flower and Tree Blue

1. Fruit collection and de-seeding

The fully formed mature pods were collected at any time from September to October and dried in a flat place. after the pericarp was dried, the seeds were scattered naturally, and the seeds were collected by flower and tree blue, picked out sundries and stored in a woven bag for dry storage.

2. Make a bed

The soil texture is sandy loam to heavy loam and the flatter part of the soil is used as a high bed, either north-south or east-west. The gentle sunny slope can also be used as a horizontal bed. The width of the bed is 1.2-1.0m, the height of the bed is 0.15m-0.2m, and the length of the bed depends on the condition of the ground, generally 20-50m. Sprinkle farm livestock and poultry manure to the surface of the bed, and put in 500kg per 100m2. Turn the table of the bed 15~20cm deep so that the soil and fertilizer are fully mixed.

3. Seed treatment

7-10 days before sowing, put the seeds into the bottom of the container, pour 70 ℃ of water 10 times the volume of the seeds, slowly and all into the container, and quickly stir to room temperature. Pour out the water the next day, mix the seeds with 3 times the volume of sand, put them in a woven bag and put them in a place of 20: 25%, waiting for germination. The seeds can also be soaked in 25: 30 ℃ water for 24 hours 20 days before sowing, then mixed with sand and placed in a place of 5: 10 ℃ to wait for germination. The seeds can also be soaked in water for about 30 ℃ for 24 hours, and then poured out the next day. Cover the seeds with sacks and old quilts. The indoor temperature should be 25-30 ℃. From then on, plant the seeds with warm water every morning until you see the seeds sprouting and ready to sow.

4. Sowing seeds

From mid-April to early May, use plate picks to open 4cm-deep trenches along or across the bed, with a distance of 25cm. Sow the seeds in the ditch, and the distance between the seeds is about 3~4cm. The thickness of covering soil is 2~3cm, and the sowing rate is about 7kg/667m2. It can also be sown, that is, the seeds are all scattered on the bed surface, and then fully covered with 2cm thick.

Second, the culture method of flower and tree blue

The main results are as follows: 1. Select the flat land or gentle slope land with loam texture, spread farm manure on the surface, apply about 4000kg per hectare, turn the soil and ridge 20cm deep, ridge with livestock plough or tractor, ridge distance 60cm, ridge height 15-25cm.

2. Planting seedlings, the seedlings of the previous year were sown at the beginning of April, and the excessively long roots were cut, and the length of 10~15cm was generally cut. The stem of the seedling was cut with 15~20cm length, and every 3-5 seedlings were planted in one hole. The distance from the acupoint to 30~45cm, the depth of the acupoint 10~15cm, step on the solid soil after planting seedlings.

III. Disease control of flower and tree blue

1. The bed table was covered with 1cm thick rice straw curtain or Artemisia annua for post-sowing management. Spray water on the cover to soak the bed topsoil 6~8cm deep. After 3 to 5 days, when the bed is dry, spray water again. Remove the mulch when more than 70% of the seedlings emerge. If there are aphids from July to August, you can spray omethoate or dimethoate, deltamethrin and so on. After emergence to the end of August, pull up or eradicate weeds at any time. At the beginning of July, sprinkle urea evenly to the bed, the dosage of 15~20kg/667m2, if there is no rain, should spray water to prevent burning seedlings. At the end of October and the beginning of November, the bed surface was irrigated once to prevent winter drought and no snow, which caused the seedlings to dry up.

2. After planting seedlings, manage the flood and slow irrigation immediately after planting seedlings on flat land, and then irrigate again in a few days. The sloping land can leave the pit plate on the ridge surface when planting seedlings, pour enough water into the pit plate, pour water again on the third day, and seal the soil after underwater infiltration. Weed and loosen the soil 3 times during the growing season to ensure that there are no insect pests and keep the soil loose. From June to August, aphids or other leaf-eating insects were found to be harmful, which could be sprayed with enemy killing or dimethoate.

Generally speaking, as long as we take good care of this plant carefully, it will thrive. When planting flowers and trees, we must pay attention to its disease and insect prevention. The efficacy and effect of this plant is also extremely powerful, if it is used for external application, it can relieve the swelling and pain of some mosquito bites and treat some snake bites. Flowers and trees blue can also be soaked in water to drink, can treat sore throat and other phenomena. But we must pay attention to its dosage and usage, in order to avoid some uncomfortable symptoms.

The above is the relevant introduction of this article, I believe you have a simple understanding of this after reading it, if necessary, you can continue to pay attention to the No. 1 home network for more information.
