1. Substrate selection: broccoli will grow well in loose, permeable and well drained acid soil. It can be planted by mixing soybean dregs, animal manure or rotten leaf soil with soil, or adding nitrogen fertilizer to increase soil fertility.
2. Water management: to plant broccoli, the soil should be kept moist, but there is no accumulated water. It is recommended to water every 5 to 6 days. When it is dry and does not rain, it depends on the situation to increase the frequency of watering and keep the soil moist. When the rain is heavy, we should drain water frequently to prevent broccoli from getting sick.
3. Nutrient management: two or three times of mixed application of nitrogen fertilizer and potassium chloride in the rosette stage, phosphorus fertilizer and nitrogen fertilizer in the flower ball expansion stage, and boron, molybdenum, magnesium and other trace elements can be sprayed on the foliar fertilizer.
4. Light management: broccoli likes to grow in a sunny place. Sufficient light can promote the photosynthesis of broccoli, produce sufficient nutrients for plants, and make the surface of broccoli more green, beautiful and beautiful. In summer, the sunshine is strong, so we should take sunshade measures.
1. Sowing: when sowing broccoli outdoors, dig a 1.3cm pit every 8cm to 14cm, then sprinkle some seeds in the pit, cover with thin soil, and water in time after sowing.
2. Spend summer: the best growth temperature of broccoli is 14 ℃ to 24 ℃. Too high temperature is not conducive to its growth. In summer, the light is strong and needs shading. In case of heavy rainfall, drainage shall be carried out in time to prevent it from rotting.
1. Soft rot: it is easy to occur when there is a lot of rain or water. Bacteria will enter from the wounds of roots, leaves and other parts, causing the plant to rot gradually. Summer to often drainage, disease can be used after the sulfuric acid chain toxin water spray.
2. Cabbage worm: cabbage worm mainly eats leaves. In serious cases, the whole leaf will let it eat up, and its excrement will also affect the sale of broccoli. After discovery, it is suggested to mix cyanobacteria No. 6 with water and spray it evenly on the plant.
1. Toxic or not: non toxic. Buy back the broccoli to eat as soon as possible, if you can't finish eating, suggest blanching or plastic wrap.
2. Hydroponics: no hydroponics. Broccoli in the case of more water is prone to soft rot, so can not hydroponics.
