The three-dimensional planting pattern of grain, cotton, oil and mushroom of rapeseed-corn-cotton-Pleurotus ostreatus in a year and a year is provided. The cotton stalk wind shading provides suitable temperature for the growth of Pleurotus ostreatus in the later stage of cotton boll opening. The ecological environment of humidity and scattered light is conducive to the growth and development of Pleurotus ostreatus. With this planting model, the net income of 1/15 hectares (1 mu) can be as high as 3,500 to 4,000 yuan, which is 2 to 3 times that of ordinary cotton. It is also a new road for wealth for farmers. The main cultivation techniques are as follows: The middle-early maturing variety Zhongyou 821 was selected for the appropriate variety of rapeseed, Ludan 981 for the maize (98 days of growth period), and the cotton was selected for Yimai (oil) cotton and two low-yielding summer cultivars of the new phenolic cotton. 18, Pleurotus ostreatus is a new variety Pleurotus ostreatus 9818 suitable for planting in vast areas of northern China (broadcasting, flowering, antibacterial, input and output ratios are generally 1:3 to 4, and high-yield up to 1:5. ~6). Rational allocation, convergence of the rapeseed in the mouth of the Shandong region in mid-to late November, transplanting, width 160 cm wide, ditch 30 cm, 4 rows of rapeseed, Paul seedlings 45000 / ha. The corn is planted around March 20th and planted on both sides of the planted surface. After harvesting rapeseed at the beginning of May, three rows of cotton were transplanted to protect 55,000 to 60,000 plants/ha; the corn was harvested at the end of June. In the middle and early stages of cotton boll opening in November, the indoor cultivated ostreatus ostreatus was moved into the middle of the farm cotton line and covered. Films, in the middle and late November, come out of fruit. Strengthen water and fertilizer management, increase organic fertilizer rape. Years ago, the intensive use of basal fertiliser and phosphate fertilizer 350-450 kg/ha. corn. Reapplying jointing fertilizer, panicle fertilizer and granular fertilizer on the basis of applying basic fertilizer, paying attention to the application ratio of nitrogen, phosphorus and potassium, generally 2:7:1.3. cotton. Nutrient seedlings, Miao Qi, Miao Zhuang, timely transplanting. After harvesting, the rapeseed should be fed with base fertilizer, which is mainly organic fertilizer, which generally accounts for 30% to 40% of the total amount of fertilizer. Pleurotus ostreatus manages 100 grams of mushroom ingredients: 95 grams of cottonseed husks, 2 grams of phosphate fertilizers, 2 grams of gypsum powder, 1 gram of salt, and a 1:1.3 ratio of feed water to water. 85 grams of rice straw, 10 grams of rice bran, 2 grams of phosphate fertilizer, 2 grams of gypsum powder, 1 gram of salt, and a ratio of material to water of 1:1.3. The straw is first soaked in 20% lime water for 48 hours, then rinsed with water to a pH of 7-8 and drained. During the fruiting period, care must be taken not to use chemical fertilizers and pesticides. Timely harvest of rapeseed, timely harvest of mature corn, timely picking cotton, Pleurotus ostreatus in late November to next January can harvest 4 to 5 batches, considerable benefits.
