Cultivation Techniques and Crop Management Methods for Turmeric
We all know tulips, which are beautiful and warm, but the tubers of turmeric have extremely high medicinal value. After being used as medicine, its tubers have the effects of promoting qi and resolving blood stasis, clearing the heart and relieving depression, and promoting gallbladder function and reducing jaundice. With proper management, its yield per mu can easily reach five to six thousand yuan. Let's take a look at the cultivation techniques for turmeric below.
1. Land Selection and Preparation
Turmeric prefers a sunny, warm, and humid environment, so when planting, choose sandy soil with sufficient sunlight, abundant rainfall, and deep, fertile soil. This kind of soil is loose in the upper layer and compact in the lower layer, with strong water and fertilizer retention capacity. Before planting, plow it 30-40 cm deep. Harrow it finely and level it, and according to the soil fertility condition, apply an appropriate amount of farmyard manure as base fertilizer. Turmeric can be intercropped with corn, but continuous cropping is avoided, so reasonable crop rotation should be carried out when planting.
2. Propagation Methods
Turmeric can be propagated by both sexual and asexual methods, but in production, for convenience and speed, asexual propagation is generally used. When harvesting turmeric in winter, keep robust, disease-free tubers as seed, store them in a ventilated and dry place, and take them out in February-March of the following spring. Remove the soil completely, cut each tuber into several pieces, requiring each piece to have 1-2 strong buds, then dig holes at a spacing of 30×30 cm, place one seed piece in each hole, using about 150 kg of seed per mu.
3. Field Management
Turmeric generally does not need watering before emergence, but if the climate and soil are too dry, it can be watered appropriately. After watering, when the water infiltrates and the surface soil is slightly dry, loosening the soil and weeding can be carried out. When loosening the soil, hoe shallowly, not too deep, to avoid damaging the seedlings, and for weeding, it is only necessary to keep the field free of weeds. In summer, which is the peak growing season for turmeric, its water demand is very high, so it should be watered frequently to keep the soil moist, but at the same time, attention should be paid to drainage and waterlogging prevention measures during the rainy season to avoid root rot caused by water accumulation. In addition, when fertilizing, apply more phosphorus and potassium fertilizer, and topdress 2-3 times each year to increase the nutrients needed for its growth. When fertilizing, it is recommended to apply decomposed organic fertilizer.
4. Pests and Diseases
Turmeric will suffer from pests and diseases during cultivation. April to August is the period of high incidence of leaf spot disease, and soft rot is very likely to occur in June-July, so prevention and control measures should be taken. In addition, cutworms often bite off the fibrous roots on the mother ginger, preventing tuber growth and reducing turmeric yield, so prevention and control measures should also be taken.
