Radish is a kind of "ginseng" in vegetables. It has very high medicinal value. It is also one of the vegetables that people like. It can be cold-mixed, marinated and stir-fried. It can also be used in the following hot pot. The following are the high-yield cultivation methods and precautions for radish. Planters should not miss it.
1. Soil
It is better to choose sandy soil with deep soil, good drainage and loose and breathable. The pH is 5.8-6.8.
2, fertility
Nitrogen fertilizer is needed in the seedling stage and the rosette stage; the fleshy roots need more phosphorus and potassium in the rapid growth period, especially the potassium fertilizer. Generally, for the production of 1000KG radish, it is necessary to absorb nitrogen 2.1-3.1KG, phosphorus 0.3-0.8KG, potassium 2.5-4.6KG, calcium 0.6-0.8KG, magnesium 0.1-0.2KG.
3, moisture
The soil moisture content in the germination period is 80%; the soil moisture content in the seedling stage is 60%; the lotus seat period is properly controlled; after the 'shoulder', the soil is often kept moist. In addition, the soil suddenly wet and dry, easily lead to cracking.
4, lighting
Radish is a long-day vegetable. It requires medium glare and lack of light. It will lead to small leaves and the roots cannot be fully enlarged.
5, temperature
It is a semi-hardy vegetable. Seeds begin to germinate at 2-3 °C, the optimum temperature for germination is 20-25 °C; the growth temperature of stems and leaves is 5-25 °C, the optimum temperature is 15-20 °C; the growth temperature of fleshy roots is 15-20 °C, the optimum temperature is 13 -18 ° C.
6, variety type
6.1, season radish
Small radish, short growing season, and common in spring in Northeast China. In addition to the cold and hot summer season, you can plant at any time.
6.2, summer and autumn radish
Sowing in summer, harvesting in autumn, growing season 50-90 days.
6. 3, spring and summer radish
Sowing in March-April, harvesting in May-June, the growth period is 45-70 days. Most of them are medium-sized varieties with low yield and short supply period.
6.4, autumn and winter radish
The main cultivation type in the north. Liqiu is planted in the summer, harvested before and after winter, and the growth period is 70-120 days. Strong cold resistance and large fleshy roots.
6.5, winter and spring radish
It is mainly planted in areas such as the Yangtze River basin where winter is not too cold. Sowing from late autumn to early winter, wintering in the open field, harvesting in February and March.
7. Site preparation
The former crops are selected to have more fertilization and less absorption, such as beans. Deep ploughing, combined with land preparation, and applying enough base fertilizer.
8, as a 畦
Large radishes are mostly made of sorghum or high ridges;
9, sowing
"Head radish, two-vegetable dish", sowed about 10 days earlier than cabbage. On-demand or strip-on can be used. When ordering, dig 3CM deep holes on the raft, and 3-5 seeds per hole. When broadcasting, open a 3cm deep ditch on the raft and sow the seeds in the ditch.
10, and time seedlings
The seedlings can be divided into 3 times. For the first time, when the cotyledons are fully hypertrophy and the true leaves are at the top of the heart, 2-3 strains per hole will be left on the spot, and 1 strain will be left for every 3 cm in the row; the second time in 2-3 true leaves, Choose a good seedling to stay. The third time in 4-5 true leaves, seedlings, leaving 1 plant per hole.
11, reasonable watering
Watering immediately after sowing, wait for the seedlings to be unearthed, then water again. In the early stage of seedlings, small water can be poured. Stopping watering before harvesting can improve meat quality and storage performance.
12, top dressing
In the base fertilizer, the amount of phosphate fertilizer is sufficient, and the topdressing fertilizer is mainly nitrogenous fertilizer, which is generally chased 3 times, respectively in the seedling stage, the pre-expansion period and the rapid expansion period. The second and third times can be combined with phosphorus and potassium fertilizer. It is best to apply compound fertilizer 25-30KG/HM. If necessary, chase some potassium fertilizer later, preferably foliar spray.
13, cultivating weeding and soil
After the general seedlings are out, the cultivating loose soil is weeded every 10 days or so. After the last ridge closure, stop cultivating and hand weeding.
14, harvest
The fleshy roots are fully inflated, the base has been "rounded", the leaves are lightly turned, and when they turn yellow-green, they are harvested.
There are many varieties of radish, and the time and method of planting each variety are different. If the radish that you want to grow can be high-yield, you need to pay attention to the planting method. It is very important to plant the soil, weeding, and cultivating the soil. The above is the detailed radish. High-yield cultivation methods, you can learn from.
