High-yield techniques of intercropping Ginger and Wheat with good quality

The intercropping of ginger and wheat can make full use of light and heat resources, reduce the process of planting and shading, and solve the contradiction of fighting for land for ginger grain. The average yield of ginger per mu is 2000,000kg, the high yield is 3500mur4000 kg, and the yield of @ # @ 245kg / mu is 300-4D0 kg. The technical measures are as follows:

The main results are as follows: 1. under the premise of ensuring the density of ginger, the interplanting spacing of ginger and wheat is determined. The results showed that when the row spacing was 50 cm, interplanting rows were set aside, and two rows of wheat were sown in trenches, the yield was the highest, and the shading condition was suitable for three minutes of light and seven minutes of shade. There are also in the ginger line, the withdrawal of overwintering spinach, in order to improve economic benefits.

2. Ginger needs a large amount of fertilizer for soil preparation, so before planting wheat, we should apply 5000 kg of high-quality soil and miscellaneous fertilizer per mu, 70 kg of ternary compound fertilizer, 25-30 cm deep ploughing, rake fine leveling, and make a border in the east-west direction, with a border length of one week and a width of 50 cm.

Third, the suitable time for sowing ginger should be 5 cm when the ground temperature is stable at 16mur17C. When sowing, first open a 10 cm deep ditch in the border, pour water through, and then drain the ginger seeds into the ditch with the ginger buds facing south and covering the soil 5cm to 6cm. Wheat is sown in late October and early November. The distance between ginger plants is 17ml / 20cm, and 7500 plants / mu are planted. Wheat varies with variety and sowing date, and the basic seedling is between 15 and 250000.

4. Field management 1. Cultivate strong seedlings before winter, promote early development of seedlings in early spring, apply 20-5 kg of urea per mu at the early stage of jointing, and watering to prevent diseases and pests in time to ensure high yield and harvest. 2. Ginger (l) poor shading is not resistant to light, especially in the seedling stage in early summer, the sun is strong and must be shaded. When the wheat is harvested, only the ears of wheat are harvested, leaving the stalks as shade grasses. When the seedlings are 40 centimeters high in late July, the straw is removed. In the south of planting ginger, a row of corn was planted between two rows of wheat, with a plant spacing of 40 cm, 3000 plants per mu, and fresh corn was harvested in the first and middle of August. (2) the root system of herbicide ginger is mainly distributed on the surface of the soil. After emergence, it is combined with ploughing in watering for 2 times to loosen the soil and preserve soil moisture. The growth is slow in the seedling stage, and it is also in the high temperature and rainy season, which is easy to cause weeds. Manual weeding takes more labor, and it can be controlled by herbicide, trimethoprim, fluralin and so on. It should be operated according to the instructions to avoid drug damage. (3) topdressing, watering and cultivating soil seedlings with a height of 25ml 30cm, urea 15-20kg per mu when there are 1 Mel 2 branches, 30kg / mu of ternary compound fertilizer when ginger seedlings are triple forked (before and after the Beginning of Autumn), and 30kg / mu of ternary compound fertilizer when ginger seedlings have 5 or 6 branches (early September) is the peak of ginger fertilizer demand.

After sowing ginger, when 80% of the seedlings are unearthed, the first water should be irrigated, and the seedling stage should be surrounded by small water, combined with shallow hoe to promote root development. The summer weather is hot, the evaporation capacity is large, should frequently boil water to cool down. The Beginning of Autumn enters the prosperous period after entering, the water demand is big, should keep the soil moist. Stop water and control ginger a week before harvest to facilitate storage. Boil water must use well water, clear water, do not pour washing powder, soapy water. It is also necessary to eliminate stagnant water in the fields in time.

Combined with heavy topdressing, the soil was cultivated for the first time, and the furrow was changed into ridge. In the prosperous period, the rhizome expands rapidly, and the ridge surface is often cracked, so it is combined with watering to cultivate the soil at any time, to about 30 cm, to create suitable conditions for rhizome growth.

(4) Disease and pest control at seedling stage, spray 1000 liquid to control corn borer and other pests. Underground pests are controlled by methyl isosulphate and Shennongdan. Ginger blast was irrigated with 80% aluminophosphate 300 times, 70% chloramphenicol 1000 times, or 70% formaldehyde 100x solution. If a central diseased plant is found in the field, it will be pulled out immediately and taken out of the field for centralized destruction. The disease points were treated with raw lime powder or bleach powder.

5. Harvest 1. At the end of wheat wax ripening, only wheat ears were harvested and left as shade grasses for ginger, which were harvested before June 10. 2. Ginger (l) Ginger: if the market is in short supply, you can take out ginger before and after the Beginning of Autumn. That is, in the north of the ginger tree, gently remove the soil of the plant with a small shovel, expose the old ginger, press and hold the connection between the main stem and the plant ginger with your hand, insert a shovel knife on the front of the ginger and tilt it up, separate the ginger from the main stem, seal the beautiful plant with it, and connect the soil with the root of ginger. Braised ginger causes wounds, which can easily lead to bacterial infection and root rot. Ginger should not be harvested ahead of time in rainy or disease areas. (2) harvesting and storage of new ginger: after Frosts Descent, the aboveground parts were harvested when they were not frozen and withered. Choose no wind and sunny morning, after digging, break off the ginger seedlings from the base of the stem, then transport them back, put them indoors or cellars, or layer them in the hole with sand, and do not need to air, otherwise the drying of the outer skin will affect the quality. Breathing is exuberant within 10 days after admission, the wound produces healing tissue, and the concentration of carbon dioxide is high and cannot be sealed. Ten days later, the hole was sealed with soil, leaving an air hole at the top. The new ginger is cooked for a month, so that the wound of the bud (stem) heals, and the tip of the bud ends with a round head. According to the needs of the market, listed one after another.
