It was planted in July, harvesting three knives on National Day, New Year's Day and Spring Festival, and producing over 10,000 kilograms per mu. The per mu output value reached 10,000 yuan. This is very popular with vegetable farmers.
(I) Selection of varieties and sowing dates Jiaxing Baigen (Xuejing) or Henan 791 must be selected for variety selection. Other varieties are not suitable. These two species have a short resting time in the fall, and the leaves do not need to be dry. They can continuously produce leeks from autumn to winter. If this species is used to detain frozen root vegetables, that is, dry ground and enter the winter, a large number of dead seedlings will occur. There have been many such phenomena in production. This is due to farmers' unclear understanding of the wintering of these two varieties. However, these two varieties are suitable for continuous production in autumn and winter. Sowing period is mid-July. Jiaxing Baigen uses 4-5 kg ​​of seed, and 791 mu of Henan uses 3.5-4 kg of seed. Late sowing needs to increase the sowing volume by 1 kilogram. When transplanting seedlings, the seeding rate should be reduced by 1 kg.
(2) Seeding and Transplanting Methods Mu Shi quality farmyard fertilizer 4 wagons, 10 kg of diammonium phosphate, 7 kg of potash fertilizer, and deep turning. The ridges are arranged in rows of 35 centimeters. Step on the ridge and ditch, and use a four-tooth rake to flatten the ridge width by 10 cm. Spread the seeds in the ditch, and use a new hammer to sweep the cover to cover the soil. Drench the water and cover with straw or straw. In addition to the above-mentioned live broadcast method, seedling transplanting can also be used. The seedlings are neat and can save some seeds. Each mu of greenhouse requires 10 square meters of 20 seedlings, each sowing 0.15-0.2 kg. Mu 500,000 seedlings. Nursery crickets should be used flat rakes, seedlings easy to transplant seedlings. Transplant 3-4 leaves, watering 1-2 days before planting. When transplanting the seedlings, use a cutting knife to press 6-7 cm to shovel the seedlings, and then put them in a flat bottom soil basket, transport them to the production plots, lay them horizontally in the furrows at a distance of 6 cm between the diurnal, plant the irrigation water, and make the ridge help floating soil sink and bury Live in the root system. Keeping the depth of the seedlings consistent, but not too deep to affect the slow seedlings.
(3) The management during the cultivation of roots should promote the transfer of nutrients to the root system and promote the delivery of crops. It is not appropriate to harvest at the time of summer and autumn. Fertilizer management and loose soil cultivation should be carried out in a timely manner. When the leaves grow too prosperous, in order to prevent the disease caused by lodging, leaf blades can be cut 8-10 cm above the leaf sheath, and the soil moisture can be properly controlled to avoid leggy growth. Pay attention to drainage during the rainy season. After the beginning of autumn, the weather was cool and the rainy season was over. Cats were excreted in urine or 20 kg of diammonium phosphate. Combined with ridges to enhance water management, keep the ground see dry see wet.
(4) Before constructing the greenhouse harvesting and its management, it is necessary to build a gable before the first frost and a back slope on the back wall to install the front roof arch. In the first half of October, the film was buckled. According to the market demand, a knife can be harvested in advance, covering the film after germination, or covering the film immediately before harvest. The outer temperature of the film is high at the beginning of the film period. Excessive ventilation must be strengthened to prevent leggy. Not only the front foot must be opened, but also the ventilation opening should be provided at the back wall of the back wall, and the convective wind should be released overnight. Do not exceed 25°C during the day and 10°C during the night. Try to keep the room temperature no lower than 5°C. When the room temperature is up to 5°C during the night, cover grasshoppers and paper sheets. The normal growth of leeks to prevent diseases. Regardless of live broadcasting or transplanting seedlings, summer and autumn have not been harvested. The withered old leaves are wrapped with pseudo stems, which affects the appearance of the product after harvest. Or use the top-dressing irrigation for more than 20 days before harvesting, the high soil to rot it, or the harvesting of bundles, and remove the water from the fake stems. Harvesting will take place on National Day, New Year's Day and Spring Festival. Each time harvesting should not be too deep, it is best to knives 5 cm above the root (bulb). After the last harvest, the roots were cut off and the fruit and vegetables were planted in order to be able to cut as deep as possible. When harvesting, we must also pay attention to market demand and cooperate with short-term storage.
In order to make full use of Goji resources in Ningxia and deeply exploit the medicinal health care value, this year, the company started the deep-processing projects of high purity Goji polysaccharide and black Goji Anthocyanin, which have been identified as the Model processing enterprises of Chinese Goji Berry by the local government.
