High-yield, high-efficiency and light-weight cultivation of cotton
Light and simple seedlings transplanting refers to the use of soilless substrates instead of soil nutrients for seedlings. Seedlings, trays, and bodies of water are used as carriers for the seedlings. The three types of seedlings are medium seedlings, plug seedlings, and water floating seedlings. Nursery succession technology. Because the transplanted seedlings only have a small amount of matrix or naked seedlings, it is necessary to pour “safe water†and return seedlings ranging from 7 to 10 days.
Increased production and efficiency: Compared with the nutritional status, the light and simple seedlings represent 50% of provinces, provinces, provinces, provinces, provinces, provinces, provinces, and provinces to reduce labor intensity and increase production efficiency.
Technical characteristics: First, matrix seedlings require the combined use of nursery substrate, root-stimulating agent, water-retaining agent and leaf-protecting agent. Plug seedlings require plugs and nursery substrates, etc. It is recommended that each hole be 100 holes. Water floating seedlings need nursery trays and nursery-specific substrates. Second, the nursery facilities are small arches, vegetable greenhouses and solar greenhouses. The third is to build a bed. The bed is flat, with a bed length of 10 to 12 inches, a width of 1.2 meters, and a depth of 8 to 10 centimeters; The fourth is the selection of seeds, and the fifth is the cultivation of seedlings before planting. Half of the red stems of the young stems can increase the resistance to stress. Sixth, the spraying of “defoliation agent†before lifting seedlings can reduce water loss and wilting of leaves from the bed.
Light and simple seedlings: Seedlings 25 to 30 days old, 2 to 3 true leaves, 10 to 15 cm high seedlings, complete cotyledon, no lesions on leaves, dense roots and thick roots; red seedlings in seedlings before leaving bed Half the proportion. Transplanting survival rate of 95%, returned to the seedling spring planted 5 to 8 days, summer planting 2 to 3 days or not obvious.
Matrix seedlings: 1. timely sowing. In accordance with the seedling leaf age of 2 to 3 true leaves, seedling height 10 to 15 cm, seedling period of 25 to 30 days of the standard planting, large nursery base need to be sowed in batches. 2. Foot spasm, suitable plant spacing sowing. In the shop covered with seedlings nursery bed thickness 10 cm, sowing spacing 10 cm, spacing 1.8 to 2 cm.
Plug seedlings: 1. Closely placed two rows of plug trays on the seed bed, seamlessly. Vegetable greenhouses can be layered seedlings. 2. Matrix loading. The water-retaining agent first fully absorbs enough water and evenly puts into the bottom of the tray, then fills the seedling substrate with a small amount of water to clean the river Shaga and fills the plug tray, scrapes the flat surface, neatly lays, and prepares the seedbed for sowing. Water floating seedlings: 1. Seedling trays are porous polyethylene foam seedling trays, 68 cm wide and 6 cm long, with 200 holes per plate and 25 ml per hole. 2. Build the pool. Pool length 210 width 110 deep 20 cm, surrounded by the bottom and the whole level, with agricultural film on the bottom of the tank and around to prevent the leakage of nutrient solution. Each pool of flotation seedlings special fertilizer 1 package, 400 kilograms of water, dubbed nursery nutrient solution. 3. Germination. The seeds are wrapped in a wet towel, wrapped in a heat-preserving material for about 10 hours, and the seeds can be sown by exposing the seeds to whiteness.

High-yielding Cultivation Techniques of Wheat (Oil) After Transplanting
Wheat (oil) transplanting cotton is a new cropping pattern developed on the basis of rising food prices, mechanization of wheat harvest, and maturity of light seedlings. However, some new problems have emerged: the contradiction between wheat (oil) cotton continuous cropping seasons. prominent. Wheat (oil) after cotton transplanting period, when the temperature is high, easy to form late seedlings and stiff seedlings, aggravate late; varieties are not matched. The lack of early-maturing and late-planting varieties of early-maturing cotton requires large blindness in the production of seeds; it is difficult to cultivate older seedlings and strong seedlings at a late seedling stage; the transplanting density is too thin, which is not conducive to late-matching and dense disputes. As early as possible, the yield risk is high. Due to the late gargle and the large proportion of late-maturing late autumn peaches, the comprehensive benefits of the two crops in the cotton field are not stable. In this regard, the relevant experts put forward high-yield cultivation techniques for wheat (oil) after transplanting cotton. The comprehensive benefits of the technology are significant, which resolves the contradiction between wheat and cotton, and meets the new needs of the adjustment of the cotton planting model, which has application value.
Technical points:
1. Use medium-early-maturing and strong-bellied hybrid cotton varieties.
2. Light and simple seedlings and strong seedlings. Light and simple seedlings adopt seedling method to raise seedlings. Seedling age is controlled within 30 days. Normally, 2 to 3 true leaves are used. Seedlings use seedling growth agents. Attention should be paid to seedlings before transplanting, and red stems should be transplanted in half to facilitate survival and return seedlings. Hair tree. Seedlings of seedlings with nutrients are planted in the same period as light seedlings.
3. Plastic film covering, mechanical transplanting.
Glass Venlo Greenhouse is Spire-type glass design, design and installation of windows when more convenient and easy. Its roof slope andle can be appropriately according to the local real climate change the environment.
In Venlo greenhouse, foundation is made of reinforced concrete and the side wall is made of brick or reinforced concrete plate. the steel frame always use hot dip galvanized light steel. Roof beam adopts horizontal girder structure and using herringbone connection. The horizontal girder bears 2 or more roofs, which is made of aluminum alloy. This material is used as roof structure material and also glass inlay material. Other beams using gutter style to minimize the section. Delighting material of the roof and side wall using 4 mm thick float glass.
