So, how many months is it good to plant parsnips? How to plant toon seeds, what are the methods of planting toon seeds? Take a look together! First, the toon months planting in the four seasons can choose two seasons for sowing, spring and fall, spring sowing time is February - May this time period, fall sowing time is August - October this range, these two time periods within the sowing of the toon seeds germination rate is very high, can ensure that its thriving.
The toon likes to grow in a warm environment, so it is important to choose the time of sowing, in the south is sown in the spring and fall season.
In the north, eight to ten degrees in the spring and fall are suitable for sowing.
The toon likes to grow in a sunny and rainy environment, and excessive humidity or heat can delay germination.
Two, toon planting methods a, seed picking and seed storage toon seeds generally begin to mature in mid-September, seed picking better to choose 15 to 30 years of vigorous growth of large trees, see the capsule from green to yellow-brown, can be collected.
Collected fruit drying a few days, take out the seeds, placed in a dry ventilated cool place to save.
Two, nursery land selection and preparation of nursery land to choose fertile soil, good drainage, low water table.
Pre-plotting, more organic fertilizers, try to deep plowing before winter, after a good plot of land can be made seedling beds, seedling beds to the north-south direction is good.
The width of the bed is 1.5 meters, the width of the ridge is 0.3 meters, the height of the ridge is 0.15 meters, the bed should be flat, the soil should be fine.
Three, soak the seed germination toon seed skin hard, the surface has wax.
Live is not easy to absorb water, germination difficulties.
For this reason, before sowing, the seeds should be soaked and germinated to promote seed germination.
First deflated to remove impurities, and then rubbed off part of the wax on the seed coat, and then put the seeds in the tank (about up to one-third of the depth of the tank) with warm water (water temperature of about 45-47 ° C) soaked for a day and a night.
Fish out the already swollen seeds drenched dry, placed at room temperature to germinate.
To be rinsed with water once a day, 5-7 days later, the seeds can break the embryo white, then you can go down to the ground to sow.
The seeds treated with warm water germination can improve the germination rate in the field.
Four, sowing season toon seedling sowing time should not be too early or too late.
Too early, the ground temperature is low, delaying the seedling emergence time, easy to be harmed by late frost.
Too late, shorten the growth period of seedlings, affecting the growth of seedlings and the degree of lignification.
Based on experimental observation, the city is generally more appropriate in late March or early April sowing.
Five, seeding and mulching before sowing, the seedling beds should be filled with water, to be all the water seepage, the seeds will be treated with 15-20 times the weight of the seed of fine sand or finely shredded garden soil and mix, evenly spread in the seedling beds, can also be sown in strips, rows spaced 25 centimeters.
Use 2-3 kilograms of seed per mu.
Then cover with fine soil, mulch thickness of 0.5-1 cm.
Six, seedling management after sowing, keep the seedbed temperature 20-25 ℃, about 7-10d flush after sowing, at this time the toon seedling root system is less, spraying 15-20 ℃ warm water, daytime temperature is maintained at 20-24 ℃, the night temperature is maintained at 15 ℃ or so, with the rise in temperature can increase the amount of ventilation, when the outside air temperature stabilized at 10 ℃ or more, can be withdrawn from the thermal insulation coverings, in the open field The conditions of seedling refining.
Seedlings 2-3 leaves time seedling once, 4-5 leaves when the seedling, cultivate one-year seedlings should be 20cm25-30cm spaced seedlings, stay seedlings 150,000-210,000 plants/hm2.
When the seedling height of about 10cm can be moved into the field nursery.
Transplanting should be according to the row spacing to open about 5cm deep ditch, and irrigation along the ditch, at the same time every 10d or so in the evening when spraying 3g/kg of urea solution.
Mid-June to mid-August is the fast-growing period of the annual seedlings, this period to strengthen the fertilizer management, generally nitrogen-based fertilizer, and with the application of a certain amount of phosphorus and potash fertilizer, each time the application of urea 150-225kg/hm2, diammonium phosphate 150kg/hm2, with the appropriate amount of potash fertilizer.
After entering the second half of August, should increase the application of phosphorus and potassium fertilizer, less nitrogen fertilizer, can be sprayed every 10d 1 time 3g/kg of potassium dihydrogen phosphate solution, *** spray 3-4 times, in order to promote the accelerated lignification of seedlings, and the formation of full top buds.
Now, the knowledge about the toon planting I believe you already know, then, want to know more about the content of the agricultural industry, you can pay attention to WeChat public number: huobao3456tv to learn more about it, attention to the message can also be left to reply to the industry you want to know information.
