Management measures of post-autumn ginger

After the Beginning of Autumn, the weather was cool and entered a period of rapid expansion of ginger, in which there was more demand for water and fertilizer and more occurrence of diseases and insect pests, which was also a key period for prevention and control, so it was very important to strengthen the management of ginger in the middle and later stage. 1. Watering ginger likes to be moist but not resistant to drought, so it is generally appropriate to water it after shallow hoeing and loosening the soil. In case of drought, watering times should be increased, but do not flood irrigation. September is the best time for ginger rhizome growth, and the demand for water is obviously on the high side. Watering every 7 to 10 days is appropriate, and Rain Water should be watered less when there is too much water. Watering time should be in the morning and evening, and try not to water at noon. two。 Topdressing ginger has a long growing period and needs a large amount of fertilizer, especially in the middle and later stages of ginger, which accounts for about 80% of the whole growth period. After the Beginning of Autumn, combined with pulling out weeds or dismantling ginger shed for topdressing, it requires adequate fertilizer, comprehensive nutrition and long-lasting fertilizer effect. A fertilizer application ditch was opened on the north side of the ginger seedling 15-20 cm from the base of the plant, with a depth of 10 cm. 70-80 kg of rotten bean cake or 500 kg of rotten dung was applied per mu, plus 30 kg of ternary compound fertilizer of nitrogen, phosphorus and potassium. The fertilizer was spread evenly in the fertilizer ditch to cover the soil, and then watered thoroughly. In the first and middle of September, when the ginger seedlings had 6-8 bifurcations, the rhizome expanded rapidly, and topdressing could be carried out according to the plant growth. The general application of 4kg nitrogen fertilizer per mu, combined with topdressing to supplement boron fertilizer, zinc fertilizer and other micro-fertilizers in time, zinc sulfate 2kg and borax 1kg per mu play a very important role in improving the yield and quality of ginger. 3. The soil should be cultivated many times because the growth of ginger rhizome needs dark environmental conditions. General soil cultivation 2 or 3 times, the first soil cultivation in the big topdressing, with soil cover farm manure as appropriate, not too thick, so as not to affect the growth. After 15 days, the soil should be cultivated for the second and third time, and finally the soil should be ridged, and the rhizome should not be exposed to the ground.
