Recently, short videos have been made of the tanners from their balcony garden, “big harvest”, which is so green and sour that the tomato tumbles. People say, "what kind of food is this? It's open! In fact, the secret of many masters is hidden in the kitchen -- little soda. This bag of a few bucks of "gods" works better than professional fertilizer and pesticides! Today, let's talk about how little soda can turn into a "growing recipe" in the light of the expert agricultural perspective and practical examples。
I. Why is little soda a little bit of a gold? Scientific principles
Sodium bicarbonate is itself a weak alkaline substance, while most vegetable pathogens (e. G., powdery, frost) are acidic. Small sodium water sprays can briefly alter the ph of the face of the leaf and inhibit the growth of fungi spores. The beijing academy of agroforestry plant protection institute has shown that a 5-percent concentration of small soda water can be more than 60 per cent effective in the fight against pollinosis and not harmful to vegetables。
In addition, small sodas can decompose the stains and residues on the face of the blades and promote photocosm; when paired with salt and beer, they can be more synergistic - - the salt rises to permeate the pests, and the amino acid and sugar fractions in the beer supplement the foliage。
Two or three moves of "standing man's hand."
Disease-resistant spray: chalk disease, frostic “xin”
Formula: 15 grams of small soda (about a spoon) + 30 pounds of clean water (about 15 litres)。
Usage: spraying leaves in the morning two to three times a week。
Case in point: the cucumbers of the shandong vegetable farmer, ms. Lee, were affected by powder problems and, after experimenting with this method, the leaves faded within a week. She shared the saying, "it's $80 less than buying pesticides, and don't worry about pesticide residues when picking up."
Natural insecticides: larvae, aphids “wind-run”
Formula: 20 grams of small soda + 10 grams of salt + 30 pounds of water mixed to total dissolved。
Practising: salt dehydrating insect cells, with small sodas destroying their skin protection. Caution: spray with the sun in order to avoid burning blades, which needs to be supplemented after the rain。
3. Green leaf nutrients: oily leaves wax
Formula: 15 g small soda + 20 ml beer + 30 kg water。
Key: yeast and sugar in beer can feed the leaves, while soda promotes absorption. The master master of shanghai metropolitan farm certified that: “three days after the blowout, there was a marked increase in the size of the lettuce leaves and a 20% increase in production.”
Three, avoid these pits, double the effect
Ban 1: not mixed with acid substances such as vinegar, calcium perphosphate, otherwise neutral。
Ban 2: do not exceed the level and avoid soil alkalinization. The plant suggests a few leaves to be sprayed first。
• optimistic timing: prevention before a high onset of the summer disease or immediate use when a small number of symptoms are found。
Iv. Extension techniques: alternative creative uses of soda
1. Sterilization of seeds: 10 minutes of immersion with 5 per 1,000 small soda before seeding, with a 20 per cent increase in lumber rate。
2. Deodorant of composting: sodium is spilled into the rest of the cooking composting, soot is reduced and fermentation is accelerated。
3. Soil improvement: a small amount of soda is distributed quarterly for acidic soils (e. G., pellets of tomatoes)。
A pack of little sodas with little money to do big things, with high environmental productivity. Who says that food has to be bought and sold? The pleasure of intelligent farming is hidden in the details of life. Have you ever tried a little soda?
