1, clean the garden: the end of March will be asparagus fields litter, weeds cleared, brought out of the field burned or buried. 2. Rinse irrigation: After clearing the park, select the eye for good weather in late March. Open the roots of the plant and dry the roots. Apply 50% carbendazim 0.5kg to 100-150kg per acre to irrigate the roots. 3, water and fertilizer management: If the weather continues to dry, you can interlace small water, avoid flooding irrigation, in case of rainy weather, timely drainage, reduce soil moisture, create an ecological environment that is not conducive to disease; 6 / mid-top chase Shi Zhuang When bamboo shoots are fertilized, organic fertilizers and phosphorus and potassium fertilizers should be added. Partial application of nitrogen fertilizers should be avoided in order to enhance the disease resistance of the plants. 4, to seize the infestation of young shoots for drug protection (1) New mother stalk: 5/upper mid-term When the length of the mother's stem is 15cm high, 50% carbendazim or 40% bromine bacteriophage is applied 40 times to prevent shoot blight. (2) Female stems after branching: At the initial stage of stem blight, the following agents were used alternately: (1) 50% of mycetobacilli 2000-3000 times; (2) 10% difenoconazole water dispersed particles Agents (Worldwide) 1500 times; (3) 50% acetaminophen 1500 times; (4) 50% carbendazim 500 times spray. The application interval should be controlled flexibly according to the weather: continuous sunny days will be around 15 days, and rainy days can be shortened to 5-7 days. With low-power, miniature size, the serial communication department range sensor with mm accuracy can measure up to 20m, 40m, 60m, 100m, 150m, 200m.
