How to increase mulberry silkworm production and efficiency

First, seize the opportunity to reproduce brilliant. Sericulture and silk industry is one of the important pillars of local economic development, and it is also the main way for silkworm farmers' friends to become rich and affluent. With China's accession to the WTO, the silk industry will regain its splendor and its prospects will be bright. As long as it reaches 4 silkworms per acre of mulberry, each silkworm yields 30 kg, which is more than 120 kg per mu mulberry yield, and 600 metre or more can be protected, which means that each mu is planted. The income of mulberry mulberry can reach more than 1,500 yuan, plus intercropping income, the income per mu can reach 2,000 yuan. Second, how to make mu sericulture reach 4? 1. Choose a mulberry field: Choose to establish a high-quality, high-yielding mulberry garden. It is generally advisable to choose two dry lands or fields that are not suitable for planting rice, and use square grids (fermented dumplings) to raise seedlings, plastic film covering one-step gardening techniques, and building high-yielding mulberry fields. 2. Proper and close planting: The planting density of Mu Sang should reach 1300 strains, that is, planted at a planting density of 4 feet wide, 2 feet narrow, and 1.8 feet long. 3. Grafting and rearing: Mulberry seedlings must be bred into strong seedlings, and the seedling diameter should be 1.5 cm or more. From the 6-inch distance from the ground, the main trunk should be cut downward and adopt spiral method to pick up three spike buds. When the seedling diameter is 1.2 cm or more, two spike buds should be connected at the 5-inch and 6-inch mouths. If the seedling diameter is more than 0.7 cm, one ear bud can be connected to the root neck; the number of grafted ear buds should reach 2.5. The grafted good mulberry varieties mainly use Tongxiang Qingchuan 852, Xiang 8920, Xinyizhiyu, etc. The Liangsangliang method can develop a rapid, high yield mulberry garden. 4, fertilizer management: "Water is fat, fat is Jin." The dense planting mulberry garden should apply 100 kg of urea (including 40 kg for spring and summer and 20 kg for autumn), 150 kg of superphosphate (50 kg each for spring, summer, and autumn) and 50 kg of plant ash (15 for spring and summer). Kilograms, 20 kg in the fall). Apply sufficient fertilizer in the winter. In the year of grafting, 1/3 of the above total amount was applied, and 2/3 was applied in the second year, after which it was applied in full. 5. Pest Control: Clean the mulberry field in winter, weed the soil, plug the wormholes, and brush white trunks. When the mulberry sprouts to 2-3 leaves, use 1000 times of dichlorvos and triamyltrimethylsilyl alcohol to spray the mulberry field and implement the system of prevention and control; During the period, pests were mainly killed manually and combined with drug control. After the late autumn silkworm was over, the pesticides were sealed with pyrethroids. 6. The total effective length of Mu Sang should reach 8000-9000 meters. That is to say: 1300 acres of plants and 2.5 branches of grafted branches are 3 meters long and 9,000 meters long. The effective length of mu mulberry reaches 9000 meters, and the annual output of mulberry leaves is 0.25 kilos per mu. Mulberry produces 2250 kilos of mulberry leaves each year, which can reach the level of 4 mu of mussels. Third, how to ensure that the yield per silkworm reaches 30 kg? 1. Adhere to the Small Silkworm Co-Education: “Cultivate 70% of small silkworms”, and the management of co-education should be implemented according to the “Technical Specifications for Small Silkworm Co-culture”, and strictly co-develop the customs. To ensure that the number of heads of ants in silkworm rearing can not be less than 2,200 heads, and no disease-free silkworms, well-developed, weakly small silkworms should not exceed 1%. 2. Large silkworm labor-saving rearing: With the implementation of the construction of the sericulture village (society) in our city, the sharp increase in the number of sericulture and the contradiction between sericulture facilities are becoming more and more prominent. The solution is: 1Simple activities: Silkworm and Taiwan: Purchase Finished simple activities silkworm table, hanging in silkworm housing or under the eaves for feeding; 2 ground education: the ground cleaning, disinfection, sprinkle a layer of lime, and then lay a layer of short-stem rice padding about 3 - 6CM, and then 4 Instar silkworm rearing; 3 outdoor scaffolding: in the open space behind the house in front of the house, with a bamboo, straw curtain 3 meters high, 4 meters wide (length in accordance with the amount of silkworm rearing) silkworm shed in the silkworm shed No matter which method is used, silkworm silkworm breeding area must be more than 35 square meters. 3, strict disinfection and disease prevention, preservation of silkworm head. 1 The communal households must have matching disinfection soaking tanks, and the sericulture households must have dedicated silkworm sand treatment pits; 2 Silkworm silkworms should be prepared according to “sweeping, dipping, brushing, scraping, washing, drying, and eliminating” before silkworms. Disinfection and environmental protection; 3 small silkworms adhere to formaldehyde-proof powder and bleaching powder and anti-stiff powder are used to disinfect silkworm silkworm seats once a day. Large silkworms use bleaching powder or fresh lime powder to sterilize silkworm silkworm body twice a day; 4 Take care to prevent rats Harm to ensure that no less than 18,000 heads of silkworms are planted on the cluster. Fourth, how to make silkworm cocoons and silkworms up to 600 meters? 1. Strengthen the management of the 5th ingestion age and be ventilated and breathable. 3 days after the 5th instar sleep, it is an important period for the synthesis of the silkworm's silk glands. Don't lose the leaves and hung the food. To make fresh mulberry satiation, do not add ecdysone. 2, to strengthen the management of the cluster. 1 Each breed of silkworm farmer should have 30 to 50 square meters of special cluster room, the cluster room should be vacant circulation, easy to remove moisture, light uniformity, the use of cardboard box clusters in the cluster; 2 suitable cooked on the cluster can not be partial old and tender ; 3 do a good job hanging clusters, strengthen ventilation management. The temperature, humidity, light, and gas in the 4 clusters all have a close relationship with the relaxation. In particular, the wetness in the clusters will severely punish the influence of relaxation. The temperature in the cluster is kept between 24 and 26°C, and the humidity is 3 to 4°C, which is suitable for dryness and humidity, and the ventilation and humidity are enhanced. Conditional fans can be used to increase the airflow. 3, reasonable purchase and sale. It is forbidden to pick fins and tender fleas on picks. In the process of transporting and selling oysters, air cages must be placed, plastic bags must not be shipped and transported, and steam and heat must be prevented. It is divided into two categories, namely, sales and sales. China Agricultural Network Editorial Office
