In March, there were two solar terms: “shock†and “spring equinoxâ€. The temperature continued to rise this month, but there were more rainy days and the weather was cold and warm. At the beginning of the second half of the year, the temperature gradually stabilized at 10 °C, and the effective accumulated temperature of crop growth began to accumulate.
1. Field crops. 1 rapeseed: pay attention to clear communication channels to prevent waterlogging. For the growth of the good, the bottom of the fat foot, the topdressing more can be less appropriate to apply fertilizer, so as not to cause fat damage, and vice versa, should be appropriate. Sclerotinia sclerotiorum can be sprayed with 40% sclerotium 2000 times solution or 50% chlorhexidine 1000 times solution. The mites can be sprayed with 10% of the net 2000 times. 2 Early rice: Select resistant varieties and pests, eliminate old varieties that have been planted for many years, have reduced resistance or have been lost; remove weeds, fallen seedlings and regeneration near the edge of the field, the edge of the ditch, the side of the canal and the rice fields before the convulsions Seedlings; early spring ploughing and watering to dissolve the fields, reducing the number of locusts in winter; removing the sclerotia from the sheath blight, removing the diseased straw that was piled on the side of the field and the ridge; disinfecting the rice seeds and the rice seedbed to prevent the rats from the field. 3 silkworm (pea) beans: do a good job of clearing ditch drainage, prevent waterlogging, timely pruning or scaffolding, skillfully apply flower pod fertilizer, at the same time, appropriate topping, promote branching. In terms of pests and diseases, we focus on controlling aphids, red bean spot, brown spot, pea rust, brown spot, and pea. At the same time, do a good job in the field of rodent control.
2, vegetables. 1 greenhouse winter vegetables: pay attention to ventilation and dehumidification to prevent disease. Botrytis cinerea is still the main disease of this month. In addition to normal prevention, you can add some gray mold or valence in 2,4-D. By using the flowering effect, it can effectively reduce the humidity when the petals are wilting. Prone to mold causes the occurrence of gray mold in the fruit. 2 greenhouse early spring vegetables: it is best to use seedlings to sow seedlings, pay attention to seed disinfection before sowing. Watermelon, cucumber, etc. have entered the stage of seedling growth. In case of sunny weather, the temperature in the greenhouse rises rapidly. Before and after noon, the air can be properly ventilated and the sun can be used to remove harmful gases and photosynthesis. In addition, it is necessary to pay attention to the prevention and control of pests and diseases, such as gray mold, early blight, cucumber blight, blight and seedling damage, etc., while also preventing frost damage, wind damage, and refining the seedlings before planting. 3 Open field vegetables: Open leaf vegetables and root vegetables have entered the late growth stage. At this time, the cabbage butterfly begins to hatch larvae in the back of the leaf, and should catch the characteristics that the larvae are easy to be killed at the young age, and use the pesticide to spray the leaf back as soon as possible. . In addition, it is necessary to strengthen the work of measuring pests and diseases, and to complete the maintenance and preparation of pesticide protection machinery.
3. Orchard. 1 citrus: continue to pruning, at the end of February, the unclear garden should be cleared in time in early March, use 0.5 Bomei stone sulphur or citrus clearing special agent; the disease is mainly anti-anthrax (optional 50% methyl) Topazin WP 500-800 times solution, or 50% toxic WP 1500 times solution, scab disease (optional 40% polysulfur suspension 300-500 times solution, 50% carbendazim WP) 1000 times, 70% methyl thiophanate WP 800-1000 times); pests mainly prevent mites, white mites, leaf beetles, 3% acetamiprid 1500 times +90% trichlorfon 800-1000 times Liquid + 2.5% deltamethrin EC 3000-4000 times. 2 Li: Continue to do the pruning work, and spray 2-3 waves of sulphur sulphur mixture before the germination in early March. Weeding can be manually removed or sprayed with glyphosate. 3 peach: untrimmed grasping and pruning; if the Qingyuan chooses the bud scale to crack, it sprays 3 waves of stone sulfur mixture, which can effectively prevent brown rot; etc.; control aphids, a little leafhopper can spray 1500 times of omethoate.
4, sericulture. Ditch drainage, remove weeds; spring mulberry selection should be cut before mulberry germination, and cut of mulberry mulberry should be as neat as possible; due to temperature rise, mulberry scorpion begins to move, should use "Sang Bao" spray on sunny days 1 bag per backpack, spray the foot through the mulberry tree fist and branches; if there is mulberry mulberry damage, you should also choose sunny spray control.
5, tea garden: ditch drainage, so as not to cause water damage. After the "shock" solar terms, the tea tree should grasp the application of germination fertilizer (usually based on nitrogen, phosphorus and potassium compound fertilizer) and apply it around the root system. At the same time, it is also necessary to pay attention to cutting the diseased branches and dead branches in time before the buds sprout.
