Turmeric planting method, turmeric planting method

Turmeric, scientific name Dioscorea zingiberensis (Dioscorea zingiberensis also known as, fire head root. China is the origin of the shield leaf potatoes, more than 2,000 years ago in the "Classic of Mountains and Seas" there is a record of "Jingshan, looking at Shaoze in the north, its grass is more potatoes". Diosophores is a perennial herb in the family Diosaceae, which has the highest content of diosgenin in the world.

Cultivation techniques. First, the root system of turmeric is underdeveloped, the distribution in the soil is shallow, the ability to absorb water and fertilizer is poor, and it is not tolerant to early and waterlogging, so the ginger field should choose a slightly acidic soil with deep soil, rich organic matter, water and fertilizer retention, and can be irrigated and drained. The rake is finely leveled, and sufficient basal fertilizer is applied.

Second, the cultivation of ginger seeds and strong buds before sowing to dry ginger trapped ginger, after the sun-dried ginger seeds into the pool with bricks and wooden boards casually fenced in, the bottom of the layer of grass, put the ginger seeds in, cover with cane or old blankets, and spray a new high-fat film, so that the young shoots of ginger can be promoted to germinate quickly, and the seedlings emerge quickly and neatly.

3. Standardized management Turmeric is a shallow-rooted crop, so it should not be cultivated in depth, so as not to hurt the roots. In the seedling stage, due to the rain and lush weeds, it is necessary to carry out shallow tillage and weeding in a timely manner to prevent damage to the roots and seedlings, and keep the soil loose and breathable. In the critical period of growth and development of turmeric, spraying the herb Gendalin can transport the foliar photosynthesis products (nutrients) to the roots, improve the nutrient conversion rate and loosening ability, make the rhizomes expand rapidly, and greatly improve the medicinal content.

Fourth, pest control turmeric pests and diseases can make the plant weak, poor disease resistance, virus easy to infect, according to the plant protection measures to spray pesticides to kill insects, and at the same time add a new high lipid film to enhance the efficacy; In late autumn and early winter, prepare for wintering and cold to lay the foundation for a bumper harvest and increased income in the coming year.

There are planted, and it is already very mature, Hubei has the hometown of turmeric, where the production of chemical fertilizers for the production of turmeric can greatly increase the production of turmeric, but the current turmeric market has not been opened, and the sales are not very good.

1. Soil: turmeric is suitable for growing in deep soil and loose soil, and the soil needs to be deeply cultivated for 20 to 30 cm before planting. 2. Seed selection:

To grow turmeric, choose healthy one- or two-year-old ginger cubes. 3. Planting: Turmeric blocks are planted in the soil according to the row spacing of 33 cm and the distance between the plants is 16 20 cm, and then covered with a thin layer of soil, and finally the appropriate amount of watering can be, pay attention to the planting depth between 4 6 cm, not too deep or too shallow.

PrecautionsTurmeric root system is underdeveloped, shallow distribution in the soil, poor ability to absorb water and fertilizer, neither drought tolerance nor waterlogging, soil moisture should not be too high before planting, otherwise it is not conducive to the germination of turmeric, and it is also necessary to apply sufficient organic fertilizer in the soil.

Turmeric is told to dry the ginger trapped ginger before sowing, and the ginger seeds after the sun-dried trap are put into the pool that is casually fenced with bricks and wooden boards, and the bottom is covered with a layer of grass, and the ginger seeds are put in, covered with cane or old blankets, and sprayed with a new high-fat film, which can promote the rapid germination of ginger sprouts, and the seedlings emerge quickly and neatly.

Turmeric planting method: land selection, seed selection, planting, and staring management.

1. Site selection

Turmeric is generally planted in the spring and can be planted in March-April or October-November in the fall. It likes a warm environment, not cold-tolerant, the soil of the planting site should be deep, rich in organic matter, well-drained soil, if the soil is more clayey, compacted or poorly drained, it is not suitable for planting turmeric, which is not conducive to its growth.

2. Seed selection

Planting mostly uses rhizomes to propagate, using annual tubers, which should be free of diseases and insects, full and full and dense buds as ginger seeds. If there is rot and insect eyes on the tuber, it is easy to rot black after planting, and even the growth of the tuber in the late budding stage is very poor.

Before planting, the selected tubers should be cut into small pieces, each segment of 2-3 cm with 1-2 strong buds, so that the tubers will bud faster. The tubers should be dried before planting, and plant ash can also be applied to the incisions.

3. Planting

When planting, hole sowing and furrow sowing method can be used, the plant row spacing should be 20*15cm, and the tubers should be planted in the soil, covering the thickness of 6-8cm. It will sprout after planting for about a month, and when the seedlings grow to more than 10cm, they need to be weeded manually, and it is best to pull out the weeds.

It is not advisable to use pesticides at this time, otherwise the seedlings will die easily. And in July and August, the soil is about 10cm high, otherwise the plant is easy to lodging.

Fourth, management

Turmeric likes a moist growing environment, it is afraid of stagnant water, in dry weather, it should be watered more, but in the rainy season it should be drained in time to prevent water accumulation and rotten roots. In the seedling stage, nitrogen fertilizer should be applied, in May-June, nitrogen, phosphorus and potassium compound fertilizer can be applied, and in July, it can be combined with cultivated soil top dressing, and organic fertilizer and compound fertilizer can be selected.

Growing environment

The suitable temperature for turmeric is 15 30, the suitable temperature for seed germination is 20 25, the suitable temperature for root germination is 10 18, the suitable temperature for stem and leaf growth is 18 28, and the suitable temperature for rhizome expansion is 20 holes lead 28. The suitable temperature for rhizome storage is 5 7.

Sufficient sunlight is required throughout the growing period to facilitate photosynthesis and improve yield and quality, and the average suitable annual sunshine is 1750 2000 hours. Turmeric is more adaptable to the soil, and planting on some poor soils can also obtain certain benefits.

However, it is better to have well-drained, rich organic matter, deep soil, loose soil, and permeability. The soil with too much stickiness has poor drainage and aeration, which is not conducive to the elongation and expansion of rhizomes, and the soil with too much sand has poor water and fertilizer storage capacity. The pH of the soil is generally between 6 and 8.

1. First of all, it is necessary to choose the roots with bright color, strong vitality, no frost damage, uniform thickness, multiple fibrous roots, 2 cm in diameter, strong buds, golden closed rotten yellow or light yellow cross-section, and no disease and insect rot, and cut the new shoots from a place far away from the mother ginger. Then on the prepared furrow, according to the row spacing of 50cm (25cm along the ditch on both sides), dig a ditch of 10 to 15cm, plant the treated seed stems according to the plant spacing of 20 to 25cm, cover the soil with fertilizer, and plant about 6000 to 6500 plants per mu.

2. Fertilization, the whole process of turmeric growth should be based on organic fertilizer, pay attention to the combination of potassium fertilizer and phosphate fertilizer, and increase the ratio of n, p and k is usually 2:1:3.

There are two kinds of fertilizer for turmeric, one is base fertilizer, one is top dressing, one is base fertilizer, the other is applied before sowing or transplanting, and the other is to sprinkle 70% of the fertilizer into the soil when ploughing, and then use the remaining 30% to fill ditches or make holes. The amount of basal fertilizer is 1500-3000 kg of organic fertilizer per mu, plus 30-35kg of potassium fertilizer, 20-25kg of phosphate fertilizer, and 50kg of compound fertilizer.

3. Finally, the stem of turmeric is managed: after the turmeric emerges from the macro wheel seedling, when the stem grows to 30 cm, it is necessary to quickly build a scaffold, with one meter five to one meter, one by one, one by one, one by one, one by one, one by one, in an X-shape, used for fertilization. When the main stem grows to a certain height (m) or the side branches of the sedan leak are 20-30cm, the main stem and side branches should be cut and topped to control vegetative growth.

The harvest of turmeric is generally in autumn and winter after all withering, digging out the rhizomes from the ground, the best harvest period is from the end of November to the middle of December, rhizome cultivation is generally once every 2-3 years, the yield is higher if it is urgently needed, it can also be cultivated in the same year.

Land selection and land preparation: To plant turmeric, we should choose a field with deep soil layer and good drainage, and apply manure and farmhouse fertilizer after leveling. Rhizome planting:

Every year around the Qingming Festival of the Rubber Bureau, select rhizomes that grow well and bury them in the field with a row spacing of 40 cm and a plant spacing of 33 cm. Field management: Animal manure is applied after the seedlings grow to 13 cm.

1. Land selection and land preparation

Before planting, the soil should be ploughed 2-3 times, the clods in the field should be broken, the weeds and gravel should be cleaned out, and then the field should be leveled, and then the rotten manure and farmhouse manure should be applied.

2. Rhizome planting

Planting turmeric can be carried out around the Qingming Festival every year, first digging the soil hole in the field with a row spacing of 40 cm and a plant spacing of 33 cm, and then putting the ginger seeds without damage and disease into the soil hole, covering the fine soil, and then spraying the soil surface with a new high-fat film to improve the seedling emergence rate of ginger seeds.

3. Field management

After the turmeric seedlings grow to a height of 13 cm, they should be topped with animal manure to promote the growth of the plant, and before each fertilization, the field should be loosened and weeded, so that the fertilizer and water can be better mixed with the soil, and when the weather is dry, it is necessary to water turmeric every morning and evening to avoid the seedling leaves drying up and yellowing.
