Radish

1. Nutritional characteristics

The growth and development of radish includes two stages: vegetative growth and reproductive growth. It takes 5-6 days from the germination of seeds to the revelation of the first true leaf, during which the cotyledon and absorbing roots grow. It takes 15-20 days for the seedlings to have 5-7 true leaves from true leaf exposure to root breakage. At this stage, the differentiation of leaves is accelerated, the leaf area is continuously expanded, and the fleshy roots begin to expand. In the first 20-30 days of the succulent root growth period, the number of leaves increased continuously, the leaf area expanded rapidly, and the succulent root extended growth and coarser growth were carried out simultaneously. In the second 40-60 days, the succulent root grew the fastest, and the aboveground part grew slowly.

2, need fertilizer characteristics

Every 1000kg of radish requires pure nitrogen (N) 2kg, phosphorus (P2O5) 0.7kg, potassium (K2O) 2.9kg.

Radish seedling stage, rosette stage of the nutrient demand gradually increased, to the fleshy root expansion period of nitrogen, phosphorus, potassium absorption into the peak, during this period of nitrogen absorption accounted for 75% of the total demand, phosphorus absorption accounted for 90% of the total demand, potassium absorption accounted for 85% of the total demand, therefore, during this period to ensure adequate supply of nutrients.

Radish is sensitive to boron and calcium, boron is conducive to fleshy root expansion, prevent cracking; Calcium is beneficial to improve quality and prevent bran heart. (Taken from the network, if there is infringement, please contact to delete.)

3. Fertilization technology

Base fertilizer: 6%organic fertilizer (1-1-4, 45) 50kg+ 35%vegetable fertilizer (18-5-12) 80-90kg; Or we should apply 15% whole-cell bio-organic fertilizer (9-2-4, 25) 50kg+ We should apply 35% vegetable fertilizer (18-5-12) 70-80kg.

Spreading should be combined with ploughing into the soil or furrow or hole covering.
