Iwat cotton is growing fast, growing large, producing high and brightly coloured and highly appreciated, and today we present the techniques of plant management。
I. Preparation
1. The long life of tampons with no soil-planted tomatoes and the high demand for nutrients have led to the selection of tampons of 10 cm*10 cm*7 cm with 100 cm*30 cm*8 cm. The first use of rock cotton requires attention that it is not water-friendly in its early stages and needs to be immersed in water for more than a day. Also, since the initial ph value of the rock cotton is weak alkaline and the most suitable ph value for tomato growth is alkaline, a suitable quantity of nitrate or acetic acid is required, followed by a three-hour immersion of nutrients, which can contribute to crop growth。
2. Placing the pre-processed rock tampons on the production shelf to be prepared, with 10*10*1. 5 cm holes in the packaging of the rock tampons at a distance of 35 cm to facilitate the placement of 10*10 *5 cm of rock tm。
Ii. Standing
Cedar-free tomato planting is generally done in the morning, removing tomato seedlings from the seedlings and placing them in rocky cotton blocks, with care to protect the integrity of the root systems of the crops. Rock cotton is irrigated with drip irrigation, with a drop arrow placed on each rocky cotton block at a depth of two to three centimetres。
Iii. Post-plant management
Temperature
During the five to seven days of planting, the temperature was kept at around 25 to 28 degrees during the day and 15 to 18 degrees during the night, with the main aim of promoting slow seedlings. After a week, the temperature is reduced to avoid plant long, 20 to 22 degrees during the day and 12 to 15 degrees during the night. The temperature should then not exceed 30 degrees in the daytime, and not less than 15 degrees in the night, so as to avoid the flowering fruit and the colour imbalance. Temperature and cooling measures are taken in a timely manner, depending on weather. The winter is artificial warming, timely clean cover maintenance of light rates, ground cover of membranes, etc., to reduce moisture changes caused by evaporation。
In the summer, cooling can be done using sprays, ventilation, wet curtains, sun shades, etc。
2. Light
Rock cotton is more radiant, the winter light is weaker, care is taken to clean up the dust from the sheds in a timely manner, to ensure perceivability and to increase the light by artificial insinuation even in the sun。
3. Humidity
Rock cotton is highly developed, requires large amounts of water, maintains a base moisture of 60 to 80 per cent and air moisture of 45 to 50 per cent, and adjusts the temperature of air to weather conditions in a timely manner。
Nutritional fluid management
The trophic fluids of rock cotton soilless tomato irrigated care for low pre-flower concentrations, avoiding crop growth and high concentrations after flowering, and promoting development. Nutrition is dripped three to five times a day for about 20 minutes each, and can reduce drip irrigation during rainy days, even if it is not irrigated. Attention is paid to the three or four drops of nutrients, which can be used to drain water once, to avoid the accumulation of salt in the pipes and to block the drip arrows。
5. Plantation adjustment
The tampons are able to make chickens when they grow up to about 50 cm. And take care to remove the sick leaves。
6. Pollination
Pollination is carried out either by artificial pollination or directly by the use of greenhouses to pollute bear bees. (c) the timely removal of abnormal fruit, stunted fruit。
