西红柿银杏果实子粒防护系统

我认为西红柿果实子粒外露的主要原因是因为花器和果实在正常发育过程中无法充分成熟。西红柿花器和果实是否能正常成熟，关键取决于花芽分化的质量。我注意到，尤其是在第一、二穗果子的外露情况，这通常是在幼苗移栽期间由于高温或低温导致的。在西红柿幼苗长到6片真叶期时，它们已经完成了1、2、3、4花絮的花芽分化；当这些幼苗期的花序分化出花芽并形成花器时，如果遇到了低温或高温、水分不足或者氮肥过多，就可能会导致flower bud overdevelopment, leading to malformed flowers and fruits. Occasionally, during the nursery period or transplanting, if the temperature is too low or there is prolonged drought, with small diurnal temperature differences and insufficient nitrogen supply, the young seedlings may grow under inhibitory conditions. This can cause the flower buds to become woody and form abnormal structures when they are later exposed to favorable conditions.

These factors contribute significantly to why first and second fruit set often have exposed seeds. The growth temperature of these seedlings has a direct impact on this issue.

To prevent and control west red skin from developing deformed fruits with exposed seeds:

Choose varieties that are less prone to producing deformed fruits such as 'Red Jade', 'Red Pearl', 'West White 3', 'Jia Hong' or 'Li Chun'.

Use plant growth regulators properly. When observing excessive vegetative growth in young seedlings, do not solely rely on water control and cooling measures; instead, ensure proper management of temperatures, light exposure, water levels before spraying "Multi-purpose" at 200 times concentration or using 0.01% solution of auxin at a rate of 25% for controlled promotion.

When watering tomatoes apply deep-root fertilization by mixing 30 ml fertilizer with 15 kg water; you can also combine organic fertilizer applications with an additional dose of Angel's powder (granulated) for every kilogram of organic fertilizer added - this enhances soil permeability while boosting tomato absorption capabilities.

Upon discovering deformed fruits with exposed seeds immediately remove them; further prevention involves spraying a mixture of boric acid (at a concentration ratio of 600-800 times) combined with Indian calcium twice within two-three days for optimal results in preventing further deformities in tomato fruits.
