Tomato high yield early maturity skills

1. Potato juice germination. The potato (potato) tubers are placed in a freezer in a freezer for 3 to 5 days. After being taken out, they are naturally thawed and then juiced. The tomato seeds to be planted were soaked in potato juice for 12 hours. Use a thick cloth without fluff to pour the potato juice, loosely soak the soaked seeds on top, keep the seeds out of contact with each other, and cover them with polyethylene film to prevent drying, but keep them breathable and then put them in a warm place. After the seeds are germinated, they are inserted into the soil for seedling. According to the test, the germination by the above method can make the tomato mature 15 to 20 days earlier than the conventional method of germination. Linyi Fertilizer Network Copyright

2. Seedling level colonization. The flat tomato planting is generally shorter than the conventional erect cultivation, the slow seedling period is shortened by 3 to 5 days, the survival rate is increased by 15% to 20%, the harvesting period is 7 to 10 days earlier, and the yield is increased by 20% to 30%. The specific method is: on the basis of fine land preparation and foot-based fertilizer, the north-south direction is good, and the width is wide to cover the mulch film. Then ditch according to the line spacing, about 7 cm deep, and then dig a hole according to the plant spacing, about 5 cm deep. After the hole is made, the leaves and leaf buds of the 1/3 of the base of the seedlings are completely wiped out. The Miaoshun ditch is placed well. The roots are placed in the south facing the hole. The head is turned into the ditch in the north, and the soil is covered until the leaves are removed. The mulch is covered. The lower side branches can be cut during greenhouse cultivation to promote root growth. Horizontal planting of tomatoes should pay attention to the following two points: First, according to the height of the seedlings, high seedlings should be planted, short seedlings should be planted shortly, and the tops are not uniform; secondly, the individual plants used should be no less than 8 grams. The height of the aerial part of the seedling is about 10 cm, and it is inclined upward. Linyi Fertilizer Network Copyright

3. Foliar spray of cow urine. The fresh bovine urine is poured into the sprayer, and when the stomata of the tomato leaves are opened at noon, it is evenly sprayed on both sides of the blade, and can be carried out during the whole growth period. Generally, the yield can be increased by 18% to 25%. However, it should be noted that the cow urine collected on the same day is sprayed on the same day; during the fruit hanging period, it is not suitable to spray the cow urine for about 10 days before fruit picking to prevent the fruit surface from being contaminated.

4. Skillfully spray chicken and rabbit feces. During the fruit-bearing period of tomato, the soaking filtrate of chicken and rabbit feces at a concentration of about 6% is directly sprayed on both sides of the leaf, so that the tomato fruit can be swollen fast, mature early, good in quality and high in yield. The preparation method of the fecal liquid is: take 3 kg of dried chicken manure or dry rabbit feces, add 50 kg of water, and put it in a wooden barrel or a large tank to seal and soak for 6 to 7 days. After sufficient fermentation, stir and evenly filter. It can be used after removing the residue. Linyi Fertilizer Network Copyright

5. Press the side to remove the main stem. According to the characteristics of tomato stem vine rooting, after the tomato fruiting period expires, 2 to 3 side branches which are produced at the bottom of the main stem are left, which are bent to the ground, laminated with fat soil, and only 2 to 3 pieces are exposed at the top. Leaves, after the side branches are all fixed, water is poured once. After the beading, the temperature of the greenhouse cultivation is controlled at 20 to 25 ° C during the day, 10 to 15 ° C at night, the soil moisture is maintained at 60% to 70%, and the air humidity is 45% to 55%. After the main stem of the tomato has fallen, the main stem is cut off from the upper part of the pressed side branch, and the management of the fertilizer and water is strengthened. Generally, the side branches can be flowered in about 115 to 20 days. Linyi Fertilizer Network Copyright

6. In addition to the old branches leave the main stem. On the basis of selecting good varieties, cultivating strong seedlings, rational close planting, and fine cultivation, leave the main stem after the result and cut off the old branches. The second main stem can be germinated, and the more the fruit is, the more high-yield and long-lived tomato trees are formed. This method not only saves the seeds, but also increases the yield by about 2 times. The result is 15 to 20 days earlier. Tomatoes cultivated in open field, pay attention to heat preservation and drying, while cultivating soil to facilitate the safe wintering of plants. Linyi Fertilizer Network Copyright
