Autumn delay greenhouse how to fertilize

The late autumn cultivation of the large arch shed or the simple winter shed is affected by the climate. The growth period is only 100-150 days. In order to improve its economic benefits and extend the growth period of the shed, it must be in the middle and late July, in the environment with cooling facilities. In the middle of the seedlings, at the same time with 3-5 cubic meters of decomposed organic manure chicken manure, or 5-8 cubic meters of pig manure, combined with 30-50kg of ternary compound fertilizer. However, in the process of fertilization, if the chicken manure is not well cooked, there will be a phenomenon of burning seedlings or causing stem rot. In order to avoid such mistakes, you can choose a whole nutrient fertilizer containing organic or humic acid, such as Luhong functional organic fertilizer (containing organic matter ≥ 30%, N + P + K ≥ 4%) 120-200kg per acre plus Luhong No.1 3-5 bags (500g/bag, containing special functional factors and medium and trace element fertilizers), plus Luhong ternary compound fertilizer 40-50kg can replace chicken manure or pig manure. If dry chicken manure is applied, it is best to apply it to the soil of 30cm deep for the first 15-20 days, mix it well, ridge cultivation, watering it alternately, and cultivating it to promote further fertilization of the fertilizer. When planting seedlings, applying 40% of ethylphosphoric aluminum manganese zinc 1.5-2.0kg of fine soil in the cultivation ditch to the cultivated ridge can effectively prevent the occurrence of stem-based rot.

The crops delayed in autumn are cucumber, zucchini, tomato, celery, cauliflower, etc. In the cultivation management, in addition to selecting varieties resistant to disease and seedling heat, rational fertilization is very important. July and August are the hottest hours in summer. If the last crop is late, it is short-changing time. When applying the bottom fertilizer, do not apply organic fertilizer that is not fully decomposed to avoid fertilizer burning or causing crops. The stem base is rotted, and Luhong functional organic fertilizer can be applied 120-200 kg per mu to replace other organic fertilizers. How much fertilizer is applied is determined by the length of the growing crop. If you cultivate a crop that is only about 100 days in the growing season, such as tomatoes and cucumbers, it will not grow long after the "frost drop", but it will extend the harvesting period in a protected environment. For these crops, 100-120 kg of Luhong functional organic fertilizer and 50 kg of Luhong functional compound fertilizer (15-15-15) can be used for the bottom fertilizer. For the old shed planted for more than 3 years, there are dead trees and rotten cockroaches. In the greenhouse of the phenomenon, it is necessary to add 3-5 bags of Luhong No. 1 at the time of applying the base fertilizer, which has a good effect on preventing heavy mites and inhibiting root-knot nematodes.

After the cucumber root melon is sitting, when the first ear of the tomato grows to the size of the walnut, it is necessary to apply the expanded melon or the expanded fruit fertilizer. You can use Luhong Chong Fertilizer A+B, apply A10-15 kg per acre with Luhong Chong, interval 10-12 days, and then apply Shiluhong Chong Fertilization B; if the plant sits more melon, you can apply Lulu 18-6-26 High potassium rushing fertilizer to increase the yield in the middle and late stages. Spraying Luhong Huishenglu, Calcium Glucose, and Jinkaer Foliar Fertilizer at the same time of disease prevention can effectively improve the disease resistance of crops, heat resistance during seedling stage, and low temperature tolerance in the middle and late stages of crop growth.

Pulse Distance Sensor

Pulsed laser ranging module is a module that uses pulsed laser technology to measure distance. It emits a series of pulsed laser beams and calculates the distance between the target object and the module by measuring the round-trip time of the laser beams.PTFS has high ranging accuracy and long ranging range, strong anti-jamming ability, support for secondary development, a large number of ranges, safe for the human eye 905 nm, customizable frequency (20-3500 Hz), available for both indoor and outdoor. It can be widely used in speed measurement, displacement measurement, distance measurement and other fields.

Pulse Long-range laser distance sensors can measure distances of hundreds of meters to several kilometers, suitable for wide-area measurement and long-distance monitoring. These sensors are crucial in fields like surveying, Geographic Information Systems (GIS), mining, and drone mapping. For instance, in drone mapping, long-range laser distance sensors quickly acquire extensive terrain data, supporting the creation and updating of GIS.
