Physiological obstacles and prevention of tomato cultivation in greenhouse

(1) Malformation of malformed fruit is not complete, mainly due to poor flower bud differentiation caused by hypothermia during seedling stage. In addition, excessive soil moisture and nutrients, especially excessive use of nitrogen fertilizer, plants grow too prosperous, hormone concentration when the fruit is too high, flowering agents will form abnormal fruit shape, prevent deformed fruit must be strictly seedling management, avoid seedling long The time below 6 ~ 8 °C low temperature, the results should be reasonable after the fertilizer, hormone concentration should be appropriate to use, try not to spray pesticide when flowering.

(2) The empty fruit has ribs, little flesh, and a cavity inside. The main reasons for this are the high or low temperature during flowering, weak light, poor pollination and fertilization, and inadequate fruit development. In addition, the growth hormone treatment of fertilizer can not keep up with empty fruit, prevent empty fruit, mainly to avoid the temperature is too high or too low, enhance ventilation; master auxin treatment concentration, timely treatment after treatment to enhance fertilizer.

(3) There are three types of cracked fruit cracking, umbilical cracking and concentric tearing. Radial cracking is caused by uneven watering, frequent fluctuations, and frequent temperature fluctuations. Concentric circular cracking is due to direct sunlight and the fruit surface absorbs too much water. Umbilical cracking is due to the low temperature during flower bud differentiation. (Below 8°C) Forming of deformed flowers is cracked. The prevention of cracking is mainly because the watering should be uniform and the temperature management should be even to prevent the seedling temperature from being too low and avoid direct sunlight.

(4) Umbilical rot is mainly caused by calcium deficiency, causing the top of the fruit to turn brown. The main causes of calcium deficiency are excessive nitrogen fertilizer, excessive dryness of soil, excessive application of potassium fertilizer, and persistent high temperatures. Measures to prevent calcium deficiency include: lime in the soil, keeping the soil moist, enhancing ventilation, and reducing air humidity. In addition, it can also spray 0.2% calcium oxide solution.

(5) The reasons for leaf rolling caused by leaf rolling were early and over weight, high temperature and drought, excessive application of nitrogen fertilizer, excessive nutrient consumption during the result period, iron deficiency, and lack of manganese in the soil. Control methods: timely, moderate tip, reasonable application of nitrogen fertilizer, reasonable adjustment of the relationship between the vegetative growth and the amount of fruit-bearing, ground water, and avoid the soil too dry and wet.

Double Packed Sweet Corn Cob

A medium-sized cob of corn provides more than 10% of our daily dietary fibre requirements.
There are two types of dietary fibre - soluble and insoluble - and sweet corn contains both.
According to the American Heart Association, dietary fibre as part of an overall healthy diet can help lower blood cholesterol levels and may reduce the risk of heart disease. It is insoluble fibre that binds to cholesterol, preventing it from being absorbed into the bloodstream.
Insoluble fibre is responsible for promoting regularity and helping to prevent constipation by speeding up the passage of food and waste through the intestines and absorbing water to keep stools soft. Insoluble fibre has been shown to reduce the risk of haemorrhoids.
Fibre-containing foods such as sweetcorn also help to provide a sense of satiety and may therefore help to suppress appetite and aid weight management.
Dietary fibre has also been linked to a reduced risk of type 2 diabetes. A diet rich in fibre helps patients manage their disease.

Fibre is fermented by bacteria in the colon. Promising studies are underway to determine the health-promoting effects of fibre fermentation breakdown products, for example, short-chain fatty acids, which may help to maintain a healthy gut.
