Tomato green peel fruit is a kind of gluten rot fruit(one gallon nursery pots), leading to a variety of causes of tomato green peel fruit, the most important is the unbalanced fertilization, caused by high nitrogen and low potassium. After the tomato enters the fruiting season(36 cell trays bulk), it will easily cause green peel fruit if it encounters bad weather (low temperature, weak light), or unreasonable fertilization (partial application of nitrogen fertilizer).

Among them, the following measures can be taken to prevent: increase the application of organic fertilizers(large round planter pots), adopt formula fertilization techniques, and it is not appropriate to use ammonium fertilizers in order to adjust the proportion of nitrogen, phosphorus, and potassium in the soil to promote the absorption and utilization of potassium by plants(40 cell trays bulk). This is the most important measure to prevent tomato green peel fruit.(cheap plastic plug trays for sale australia)
Extend the exposure time of vegetables(propagation trays nz). When the fruit enters the color-changing period, it is necessary to remove the lower leaves and nearby leaves of the color-changing ears, and increase the light to reduce the occurrence of green peel fruits. Generally speaking, excessive application of nitrogen fertilizer(40 cell tray in bulk), the night temperature should be kept at 14 ℃ ~ 16 ℃, potassium Relatively too little is the main reason for the tomato peel fruit.
Generally strong roots and roots to enhance plant resistance(plant pots uk). Foliar fertilizers containing various elements (boron, calcium, magnesium, iron, zinc) are used on the leaf surface, of which the amino acid type is suitable, which promotes black and green leaves, enhances photosynthesis, and increases the absorption of boron and calcium elements(plastic planters bulk), which can be reduced Green peel, cracked fruit, etc. Generally, the temperature should be strictly controlled.
(cheap plastic plug trays for sale australia)The temperature during the day should be controlled at 25 ℃ ~ 30 ℃, and the temperature difference between day and night should not exceed 15 ℃(nursery pots for sale). At this time, we should seize the opening points of the corn before and after the 7-9 leaf stage joint to top up the fertilizer, not too much fruit set or fruit set position is too low(14 gallon pots distributor). After flowering and pollination, it absorbs more nutrients, but the absorption rate slows down.
Control the concentration of flower hormones, not too high, fertilizers should be added in time after using anthers(commercial plant pots). For sheds where green peels have already occurred, spray high potassium foliar fertilizer, chitin, etc. to relieve symptoms. There is a need for adequate nutrient supply(plastic planters suppliers). Nitrogen uptake at the seedling stage accounts for 9.7% of the total, 78.4% in the middle stage, and add water 1000 ~ 1500 kg pouring, and 11.9% in the later stage.
In order to enable summer oranges to have a high yield in winter and improve the nutritional level of the tree, it is necessary to apply fertilizers skillfully(bulk buy plant pots). Around the winter drip line, dig deep and wide 15-20 cm wide trenches, and then apply 5 to 7.5 kg of urea per mu, 10 to 15 kg of superphosphate per mu per tree over five years old(18 cell trays bulk), semi-dry licorice can also be processed into slices by manual or mechanical methods.(cheap plastic plug trays for sale australia)
Therefore, the leaves must be sprayed once every 10 to 15 days with 1.% borax(heavy duty plant trays), 0.1% magnesium sulfate, 0.1% zinc sulfate, 0.1% ferrous sulfate, 0.1% ammonium molybdate, 0.2% potassium dihydrogen phosphate, 0.3% calcium nitrate, With a 600-fold amino acid compound micro-fertilizer mixed solution, the corn plant grows fast from jointing booting to heading and flowering(15 gallon pots distributor), and it is a key period for nutrient absorption.
