First, the use of farmyard manure and organic fertilizer to produce pollution-free dates, you must use organic fertilizers after maturity such as compost, manure, cake, marsh, microbial fertilizers such as rhizobia, phosphorus bacteria, etc.; fertilizer is mainly phosphate fertilizer, potash fertilizer. The fertilization process is:
1. Early base fertilizer. Farmyard fertilizers are generally used as base fertilizers. In addition to human feces and urine, various crop straws, human and animal manure, and phosphate fertilizers can be mixed and piled up each year. After composting with aerobic microbial decomposition, the compost will be produced before the rainy season and before red dates are harvested. The ring groove can not only enhance the nutrition of the tree, but also increase the soil fertility.
2. Zaoyuan grass. According to the experience of Pangjiazhuang of Kehu Town, Linxian County, there are three advantages to the cultivation of leguminous grasses, flat stems, and radix peony in mountain date gardens. First, increase the vegetation of the jujube garden and provide biological coverage; second, legume grass Cows, goats, pigs and rabbits all like to eat, and solve the development of livestock foraging grass, jujube flowers, grass flowers is also a good source of honey; Third, animal husbandry excrement for high-quality farmyard fertilizer, aquaculture development, to solve the Zaoyuan The shortage of fertilizer sources.
3 timely fertilizer. On the basis of applying organic fertilizers, in order to meet the needs of the growth and results of Chinese jujube trees, topdressing must also be carried out. From the thawing in spring to the germination of jujube tree, before flowering to the young fruit period, organic biofertilizer can be topped up 2-3 times. The amount of mu is 200kg, which can meet the requirements of bio-organic fertilizer for 500kg of jujube in the mountain and jujube garden. . The raw materials are mainly caged chicken manure, then a certain proportion of straw powder, coal gangue powder and biological bacteria species are added, and then the chicken manure is dried and mixed.
4. Leaf spray fertilizer. Foliar spray fertilizer should be uniformly applied to foliar fertilizers containing GB/T 17419-1998 containing amino acids or GB/T 17420-1998 trace elements foliar fertilizers, diluted according to the use instructions, and sprayed during the flowering period to fruiting period of jujube trees. 3 times.
Second, agricultural measures to control pests
1. Turn the tree. The jujube gardens are mainly aimed at the damage of Prunus perenne and Zaozuobu. Before the soil is frozen, the trunk can be used as the center. Within a radius of 1m, the surface soil can be scooped up to 15cm from the topsoil and scattered in the field. Overwintering peach peony, jujube buzzing, and peach hawk moth froze to death, reducing the density of overwintering worms.
2. Winter cut insects. When pruning jujube trees in the winter, the turtle wax was cut off from the harmful branches and the egg-laying branches. The yellow-headed moths were cut off and collected and burned.
3. Scrape the rough and wrap the rope. After each year of convulsions, any jujube garden with date juveniles harmful to the armyworm will scrape off rough skin on the trunk and large branches and burn them in a concentrated manner, which can eliminate large numbers of overwintering bugs. In early September of that year, a straw rope was wound around the trunk to induce the surviving jujube of the sticky worm, which survived the scraping of the rough skin, into the grass. After winter, it was burned and burned to eliminate the remains of the jujube armyworm.
4. The trunk is wrapped around the plastic film and the straw rope is tied. Every year before the Ching Ming period, where there are jujube gardens that are harmed by jujube's footsteps and food buds, the trunks are wrapped with plastic film and straw ropes to prevent pests from getting on the trees. During operation, first put a straw rope 30cm above the trunk level, tie a straw rope, 15-20cm above the straw rope, and wrap the 20cm wide plastic film. After wrapping, tie the upper edge with a thin rope to fold the plastic film. Above the top of the two stacked over 5cm, become the bottom, the fine soil under the tree into the film to bulge, and finally the upper edge of the tight, can effectively block the mother of the moth stepper moth on the tree spawning. The straw rope that is tied down is to induce the female moths to spawn on the ropes, and the solution is burned down after half a month. It can effectively prevent the jujube from moving on the tree to eat leaves.
When it is necessary to carry out chemical control, pesticides that are prohibited from use by the State and pesticides that are not registered shall not be used. Permitted pesticides include BT abamectin, Nongkang 120, lime sulfur, chlorothalonil, etc. Attention should be paid to the use concentration and the number of sprays should be minimized.
