Greenhouse vegetable cultivation six Mistakes

　　For several days, I went into pollution-free vegetable production Henan Xinye Park - Jiaoxiang green gold garden vegetable cooperatives, listen to a dozen greenhouse vegetable greenhouse vegetable cultivation management champion talked about the experience: to get out of the greenhouse vegetable cultivation six errors, in order to yield income.

 

　　Myth one: Fertilization and more output and more.

 

　　Many farmers in vegetable greenhouses lot of fertilizer, in order to more output. In fact, excessive fertilization vegetable fat can easily cause harm. Solution: First, planted three years after the greenhouses, chicken, cow dung at 2500kg or less of the control, reduction of chemical fertilizers by 50 percent. Two large plots the entire concentration, focusing on cow dung, humic acid fertilizer and EM fertilizer to increase soil carbon and nitrogen ratio, cultivators breathable, lowering salt solution fertilizer damage. Third supplemental boron, zinc, magnesium fertilizer, soil nutrient balance, in order to reduce investment, and strive to create conditions for sustained yield.

 

　　Myth: Liumiao more high yields.

 

　　Numerous farmers tend to stay when in Liumiao that can yield more than seedlings. In fact, because of low winter temperatures, the weak light, photosynthesis is a poor, less carbohydrate synthesis, only to yield a reasonable density. Wraparound: First winter vegetable crop at a reasonable sparse as well. The second is to take full advantage of space, can be taken early planting, medium sparse lines, the late thinning management approach, in order to prevail not crowded leafy shoots to improve production and overall effectiveness.

 

　　Myth: High temperature, grow faster.

 

　　In fact, an upper limit on the temperature requirements of vegetables, usually 25 ~ 32.emperature, respiration big body running, physical activity disorder, leggy plants, unbalanced nutrition and reproductive growth, yield but will decline. Solution: First, set up two greenhouses leaked mouth, timely cooling. Second, according to the desired temperature and growing a variety of vegetables growing in various organs optimum temperature requirements management, to prevent temperature long not long vine fruit.

 

　　Myth: Strains Man prosperous, is growing well.

 

　　Most people think that a good crop strains vine flourish, in fact, more water leaves Wang, roots will be shallow, nutrient insufficiency low yields, excessive vegetative growth inevitably affect the generative growth, but lower yields. Solution: First, grasp the faint lines at the seedling stage Deep, control water control strains promote root absorption of the underground portion of photosynthetic products accounted for about 60%, in the late underground and aboveground uptake 50:50. Second, pre-strains accounted for 60% of the body consume nutrition, reproductive growth of 40%; interim 50:50; late reproductive growth of 60% to 70%, vegetative growth of only 30% to 40%, which is to ensure a certain degree of pre- assimilation leaf area, and promote post-control vine fruit, increase production.

 

　　Myth: fight drugs frequently, less disease.

 

　　Many farmers in the vegetable growing late, every 2 to 3 days to fight a second drug that drugs play ground can prevent the spread of disease. Solution: First, look for the disease, symptomatic spraying, it is best to use copper, zinc agent, both sterilization, can enhance the ability of plants to resist bacteria invade, but also to promote crop growth. Second, improve the ecological environment, flourish, poor ventilation, spank drug effect is not satisfactory, should be sparse leaves cool. Third, soil-borne bacteria that cause the death of seedlings, seedling should focus on drug prevention. If you ignore the source of the disease, seedling disease, late onset, germs have invaded the plant body, ground fighting drug effect is not good.

 

　　Myth: Stubble times more income and more.

 

　　Many people believe that investment in the construction of greenhouses, cannot let the land idle, so the deputy with the main crop stubble, stubble cover the principal rice crop, crop planting times and more, the results are often poor and less effective. Solution: First, a heavy winter crop, seed crop year as well, as the spring crop should be a year too. Eggplant, pepper, tomato and cucumber plants were regenerated renewable closing the old crop, prices are minimal lift seedlings to dry land. The second is to remain for some time in the summer every year in plowing, rain pressure salt, exposure sterilization, stuffy studio pest control, soil ripening.
