Nanchuan District Ginger Non-pollution Production Techniques

First, choose a good variety

The cultivars are selected according to different cultivation purposes. There are two varieties of ginger and rhubarb ginger commonly used in ginger production in our district. White ginger is rich in water, slightly spicy and less fiber, suitable for seasoning, suitable for deep processing and development and ginger cultivation.

2. Strictly choose land preparation, implement deep trench high compartment and reapply basic fertilizer

The ginger is warm but afraid of strong light, it is afraid of drought, but also afraid of earthworms, the harvest is also the characteristics of the underground part, so in the choice of soil, we must choose the soil depth (1.5 feet or more), drainage is good, irrigation is convenient, In the first three years, loose soil, soil and sandy loam were not grown in ginger (a three-year dry and dry rotation system is usually used for growing ginger). For the former crop, rice was the best.

Jiang Di will dig ahead to 1.5 feet. Apply 4,000 to 5,000 ounces of organic fertilizer, such as animal manure, per acre before deep digging. The sun is white, then loose, 7 feet open, and the car surface is level, so that the main ditch, car ditch and gutter are well treated, and groundwater is reduced. Bit. The ditch is 1.5 feet deep to facilitate drainage and ensure that the rain stops dry.

Third, strict selection and disinfection, timely germination sowing

Strict selection of disinfection is an important measure to prevent ginger fever. In the early March of each year, select the sunny ginger seedlings and select the ginger seeds that are full of strong growth. Spread them in the sun for 2-3 days, dip for 30 minutes with 78% of Jiangrongling 300 times and then clear the water. Wash the ginger liquid on the surface to germinate. During the germination, attention should be paid to temperature rise and heat preservation, and the temperature should be controlled within the range of 21-30 degrees to facilitate the growth of buds and prevent high-temperature sprouting. After 30-40 days, budding can be transferred.

IV. Standardized planting and reasonable management

(I) Proper sowing and reasonable close planting

According to the climatic characteristics of our region, the area about 600 meters above sea level should be sown in mid-April: the area above 600 meters above sea level should be sown in mid-April. In the early sowing, the temperature is low, easy to kill seedlings; late is listed late, the price is low, the output is not high.

Reasonable dense planting is the guarantee of high yield of ginger. The 50 million mu ginger base is mainly cultivated with ginger, and the supporting gardenia ginger and ditch ginger are matched. Nest ginger 8000-10000 nests per acre, use a special ginger shovel dig diameter 13-15? Width, 25-35? deep round nest, nesting 30?, each nest planting a piece of germinating ginger seeds, buds With the child facing upwards, tap into the mud and cover it with fluvo-aquic soil or ash and rotten organic fertilizer.

(B) film coverage, thermal cultivation

After the ginger seeds are planted, they are covered with a plastic film to increase the soil temperature. The soil around the plastic film is compacted with fine soil to facilitate warming and heat preservation, and the seedlings are quickly and homogeneously promoted. After the ginger seedlings are unearthed, they are removed and allowed to grow normally. Ginger cultivation has the characteristics of early season, high yield, fewer pests and diseases, and the provision of morning market.

(3) Top-dressing fertilizer for multiple times and scientific formula fertilization

During the entire growth period of ginger, it should be carried out several times in cultivating soil, and it should be carried out after the ginger seedlings are unearthed, generally 3-4 times. On the basis of applying basal fertilization, combining top-dressing soils for top dressing 2-3 times, the principle of vegetable combination of N, P, and K, 1-2 times of N and K fertilizers, and the last time appropriate dressing of N fertilizer and P fertilizer. . Generally during the entire growth period, mu with urea 40-60?, superphosphate 50?. 30 kg of K fertilizer, or 100% of compound fertilizer for ginger.

(D) Adhere to the "prevention-based, comprehensive prevention and control" pest control measures

The main pests and diseases of ginger in our area are corn borer and ginger borer.

Corn borer, commonly known as "rhombus", causes plant "dry heart" after the damage, begins to carry out harm in June-July, control the time to master the emergence of shoot tip, and use 800 times the enemy before the larvae have drilled into the stem to cause dead heart. Hundreds of insects spray the base, at the same time to prevent and control corn pods on the surrounding corn to reduce the source of insects.

Since ginger seedling disease is mainly caused by ginger seeds, soil, and fertilizer carriers, prevention and control measures should be taken for prevention and control. The prevention and control measures were based on the disinfection of ginger medicines and soil disinfection, and the disinfection of pesticides was mainly Jiangyanling and Jiangyanxiao No.1 and No.2. Strict selection and selection of land, implementation of deep trench high compartment, more potassium fertilizer, flood irrigation and so on. Chemical control, in the early onset of ginger, use ginger to kill 1st or 2nd agent 300 times the filling nest, once every 10 days, continuous 2-3 times, can effectively inhibit the development of ginger rickets.

(5) timely recovery

According to the purpose of cultivation and market conditions to select the harvest time, tender ginger from the beginning of August to start harvesting, for ginger seed harvested in early November. Before the dawn of the morning frost, harvest on sunny days. Harvesting is not conducive to storage.
