How can we manage the ginger season
This year, the ginger season began, and farmers are still looking for medication to control diseases such as ginger plague? How can he grow? I'll start by telling you about the biological properties of ginger:
I. The biological properties of ginger
1. Chon's roots are underdeveloped, shallow, weak in absorbent to fat water, and their roots are distributed at 0-30 centimetres of soil, with no absorptive capacity at depths exceeding 30 centimetres。
2. Ginger's requirements for environmental conditions:
(1) temperature: ginger is hot but afraid of high temperatures, is resistant to frost, is vulnerable to freezing up to 5 °c, starts to develop at 15 - 16 °c or above, is stunted at 20 - 23 °c and 26 °c, can cause death at more than 35 °c, and increases most rapidly at 12 - 15 °c。
(2) lights: ginger, cold, intolerant of strong light, requiring medium light during seedlings, otherwise vulnerable to seedlings, sprouts and tubs swelling in dark environments。
(3) water: the roots of ginger are shallow, the absorptive capacity is weak and the water requirements are stringent. In the early stages, small seedlings, low intake moisture and high humidity are not conducive to increasing the temperature of the earth and are prone to the decay of ginger. Ground-based droughts, high surface temperatures, which can cause injury and seedlings, are produced with small water loads, which are based on the dry surface. At a later stage, the above-ground seedlings grow in high demand and should be watered every 7 to 10 days。
(4) soils: chon is not strictly required for soil, either on sandy soil, or on border soil, and clay can be grown, with a growth-friendly soil ph value of 5. 5-7 for ginger。
(5) fertilizers: chon's roots have a weak absorptive capacity and the main harvest in production is ginger pellets, so the fertilization of ginger fertilizers during the magnum period has a greater impact on yields. Absorption of fat is evaluated as 4. 44 kg nitrogen per 1000 kg of ginger, 1. 29 kg of phosphorus pentaoxide, 9. 64 kg of potassium oxide, 1. 30 kg of calcium and 1. 36 kg of magnesium. The amount of nitrogen is required for the first period and the amount of potassium is required for the later period. In addition to this, a larger amount of boron, zinc and calcium fertilizer is required。
Time of seeding
The seeding can take place in mid-april, in small arch sheds in late march and early april, and in large arch sheds around 20 march。
Iii. Pre- and post-plant management
(1) whole area fertilisation: after the harvest of the former crop, field plant residues are removed in a timely manner and taken out of the field for central treatment in order to reduce the source base of the disease. A year ago, the machine was used for deep flipping at depths above 25 cm. In early march of the following year, it was found to be deep, flat, fine, clean and solid and to open a ditch at a distance of 65 to 70 centimetres and depth of 15 centimetres。
(2) base fertilizer application: based on soil fertility, 2500-5,000 kg of organic fertiliser per acre for the whole field. After opening the ditch, 80 kg of bio-organic fertilizer per acre (over 25% nitrogen, phosphorus, potassium, over 25% organic), 50 kg organic calcium, 1 kg boron, 2 kg zinc fat, 5% dix sulfur, 10 kg of particulates, evacuation in the gutter and plastering。
(3) seeding: water is filled with well-opened plots of ginger grenade, 90-150 times chromium seed is used, and seeded at a distance of 22-25 cm below water. When seeding, ginger sprouts are up, the ginger seed is set south-west (with an angle of 45°) and the dust is 2-3 cm behind it. The year of drought is followed by water again。
(4) herbicide spraying: 40 per cent of the acre area selects 120-150 ml or 33 per cent of the new ginger garlic herbs (ethyl fluoride plus diacetalrin) cream 100-125 ml/water 50-75 kg flat spray。
(5) duplicate: if the membrane is used, the membrane and the soil must be tightened and leave no gaps in order to prevent the emergence of seedlings, and if small arch sheds are used, they should be withheld in time to improve the temperature。
(6) pre-plant management: primarily temperature and water management. Ginger's teeth should be warmer, less or less watered, while the surface should be dry, the best in the afternoon。
Iv. Millennium and oada management
1 shrimp management
(i) timely defilamentation: when a membrane or small arch shed is used, if a ginger sprout is found, it should be released in a timely manner to prevent excessive temperatures and “boiled seedlings” and, in the event of a surface drought, light precipitation should be applied in a timely manner。
(2) prevention and treatment of tigers and sarcophagus: a combination of weeding and planting in china to improve temperature。
(3) shading: it is appropriate to use a black shade net 80 cm wide, with a wooden stick to cover the south and a north and south to cover the west. Avoiding the use of corn straw for ginger grass to reduce the risk of maize distress。
2. Daejeon management
Ginger's “triple horse fork” enters the boom period and is a critical period for the production of ginger's production, which is also at the forefront of management。
(i) decontamination, shade: remove the membrane or tectonic membrane when the temperature is above 18°c; remove the shaded net when the ginger itself is able to cover the shade。
(2) watering: ginger needs an increase in the amount of water required to enter the boom, which should be watered once for 7 to 9 days, keeping the surface wet. At the same time, water can also cool. At this point, water should be poured away from the high noon temperature, preferably sooner or later. Watch the drain when it rains。
(3) fat pursuit: ginger root is a meat root, with weak capacity to absorb fat, which requires less diligence. Additional potassium fertilizer and other trace elements。
(4) planting soil: the maximum depth of the length of the ginger tubing is 8-10 cm below the surface of the earth, which is too deep or too shallow to be conducive to its growth, so that, depending on the growth characteristics of the ginger, it should be prepared from time to time and kept in the ground from 8-10 cm; in the middle of the autumn, when it enters the season when the night and the day are warmer, it should be prepared in time, normally 10 days before the autumn, once at the end of the autumn, once at the end of the autumn. Make sure you're well trained。
V. Distribution management
1. Deficiencies:
In the event of deficiency symptoms, spray is performed using the relevant fertilizer of the vortex。
2. Diseases:
Chon bear disease, stasis, seltzer disease, etc.: these diseases are root causes, which are ploughed using 50-100 times chrysanthemum and 1,000 times garlic oil and 600 times vocidone。
Leaf spots, anthrax, etc.: these are leaf diseases, which are sprayed with 150-300 times garlic oil and 1,000 times vofonone。
3. Pests:
Tiny tigers, nematodes, etc.: these are underground pests that kill 2,000 times the cream with 1,000 times garlic oil, or 1,500 times the milk of 20% cyanether pyrethrin, or 2,000 times the high-efficiency chlorocypermethrin cream sprayed on the lower part of the ginger plant。
Gingertrum et al.: these are ground pests, with 1,000 times garlic oil mixed with 1. 8% avm emulsion emulsion, or 1500 times cypermethrin emulsion, or 2. 5% high-efficiency chlorocypermethrin emulsion with 2,000 times ginger sap。
