Tomato management technology in greenhouse

1. Grasp the management of the growth period. Including cultivating and weeding, water storage and protection, tying vines, pruning, removing old leaves, ventilating and lightening, strengthening pest control, and strengthening temperature management. The disease of tomatoes can be prevented from being refractory, and should be based on "prevention". Temperature management is to increase the ventilation of the greenhouse during the day, so that the temperature in the shed is kept at about 25 °C, and the temperature at night is kept between 10 °C and 13 °C. When the wind starts to be released, the air outlet should be small to large, and the air outlet will gradually become smaller or closed after the temperature drops in the afternoon.

2. Grasp the management of fertilizer and water. The growth period of tomatoes generally does not require watering in the summer and autumn rainy seasons, but when the second ear to the third ear are ripe, they should be properly watered. According to the growth of tomato plants, timely topdressing to promote fruit development, preserve flowers and preserve fruit. Compared with the non-applied tomatoes, the sweetness and yield of the fruit are much higher.

3, picking fruit at the right time. The ripening of tomatoes is green, discolored, mature, and mature. Storage and preservation can be harvested during the green ripening period. Transport for sale can be picked during the color change period (1/3 of the fruit turns red). On-site sale or self-feeding should be picked when the ripening period is more than 1/3 of the fruit turns red. It should be lightly picked and harvested when harvesting. It is best not to bring fruit stalks when picking up, in case the fruits are stabbed in each other during shipment. Before the first frost, if there are still unripe green fruits, they should be stored in the greenhouse after harvesting, and then listed after the fruit becomes ripe, which not only prolongs the supply period, but also increases the economic benefits.

Polylactic Acid PLA

Polylactic acid (PLA) is a novel biodegradable material made from starch derived from renewable plant resources such as corn. Starch raw materials obtained glucose through saccharification, and then fermentation of glucose and certain strains to produce high purity lactic acid, and then through chemical synthesis method to synthesize polylactic acid of a certain molecular weight. It has good biodegradability and can be completely degraded by microorganisms in nature after use, resulting in carbon dioxide and water, which does not pollute the environment. It is very beneficial to environmental protection and is recognized as an environmentally friendly material. Ordinary plastics are still incinerated, causing a large amount of greenhouse gases into the air, while polylactic acid plastics are buried in the soil to degrade, resulting in carbon dioxide directly into the soil organic matter or absorbed by plants, will not be discharged into the air, will not cause the greenhouse effect.
